The quality and developmental pathways in sibling relationships: A qualitative study of Norwegian children admitted to child welfare service care

Siblings are key actors in the social network of young people in care. This paper explores young people's perceptions of changes in the quality of sibling relationships and the pathways relationships follow during the transition from the biological family into care. A thematic analysis of interviews with young Norwegian people ( n = 25) in care showed that, in the biological family, sibling relationships are characterized by alliances, parentification, conflicts or nonexistence. After admission to child welfare services care, sibling relationships developed along multiple pathways. Their sibling relationships reshaped into either close and supportive, conflictual or completely broken relationships. Sibling relationships were dynamic, complex, with the pathway, and its impact on well-being, being unique to each young person. Sibling relationship quality in the biological home did not predict relationship quality after admission to child welfare services. The implications for social worker practice are discussed.

Alternatively, to compensate for marital conflict and family hostility, siblings bind together, increasing their intimacy and warmth (Fabing et al., 1956;Kim et al., 2006;Sheehan et al., 2004). In the absence of appropriate parental relationships, siblings care for each other instead (Bank, 1992;Thorpe & Swart, 1992), providing emotional and psychological support (Bank & Kahn, 1982). This is a process of parentification, namely, when young people play a parental role to provide for siblings or support the parents. Depending on siblings' age, the burden of parentification can be too heavy, turning this process into a destructive pathway that impinges the well-being of those who engage in it (Burton, 2007;Hooper et al., 2011). Meanwhile, if mature enough, siblings can gain confidence and benefit from the role (i.e., adaptive parentification) (Burton, 2007;Byng-Hall, 2008).
Sibling relationships become particularly complex if one or more of siblings are taken into the care of child welfare services (CWS).
Young people in care are connected to numerous individuals (e.g., biological parents, social workers and friends). Social work policies (e.g., Bunkholdt, 2017;Norwegian Public reports-NOU, 2018) recognize sibling connections as especially important, however, often advocating sibling coplacement. The assumption is that these ties are potential channels to exchange care/support, impacting young people's well-being. The literature shows varied and sometimes contradictory evidence supporting the outcomes of different placement histories. These include different living arrangements and placement histories (Hegar & Rosenthal, 2011;James et al., 2008) evoke different outcomes regarding behavioural problems (Hegar & Rosenthal, 2011) and academic performance (Hegar & Rosenthal, 2011), sibling conflict (James et al., 2008), attachment to the CWS caregiver (Hegar & Rosenthal, 2011;Leathers, 2005), emotional continuity and safety (Shlonsky et al., 2003) and feelings of belonging (Leathers, 2005). On the one hand, sibling bonds provide young people with emotional support during coplacement in CWS homes (Bank et al., 2004;Hegar & Rosenthal, 2011;Henry, 2005;Herrick & Piccus, 2005;McBeath et al., 2014;Richardson et al., 2017;Wojciak, 2016); and siblings may form alliances, supporting themselves when suffering together (Whiting & Lee, 2003). However, this may not always be true, with sibling relationships breaking downs when siblings are placed in the same foster (Vinnerljung et al., 2017).
Although a range of outcomes are reported, there is a paucity of research exploring the process through which the sibling ties develop, when transitioning to CWS care. Despite widespread guidance on the need to coplace siblings, little is understood of the quality of sibling attachments from the young person's perspective under such circumstances (Jones, 2016), nor how separation from the sibling impacts on these (Milevsky, 2011;Seale & Damiani-Taraba, 2017). To fill in these research gaps, we qualitatively explored the nature of these ties from young people's perspectives. We intended to contribute to current research by comparing this relationship before and after the transition and trace the pathways between these. Such knowledge is relevant for stakeholders (e.g., social workers and foster carers) facilitating this process.

| Sibling relationships in Norwegian child protection services
Norway is a useful site to examine young people's perspectives of sibling relationships after moving into care as its policies typically represent international child-welfare policies that recommend coplacement, for example, Norway (Bunkholdt, 2017;NOU 2018NOU :18, 2018, Europe (Lundström & Sallnäs, 2012;Sting, 2013), the United Kingdom (Hollows & Nelson, 2006;Jones, 2016;Yates, 2018) and the United States (Albert & King, 2008;Gustavsson & Maceachron, 2010;Ward, 1984). The Norwegian Child Welfare Act does not contain any direct provisions concerning how siblings should be placed in care other than the child welfare service should facilitate sibling contact.
The Norwegian government recommends that 'children are allowed to grow up with their siblings' (Sundvollen-erklaeringen, 2013), and it is only if it is the best interest of the child that siblings should be separated (NOU 2018(NOU :18, 2018. Despite these recommendations, in Norway, 60% of young people going into care are separated from their siblings (Falch-Eriksen, 2017). The main reason is the lack of foster/ care home places willing to take sibling groups.

| METHODS
As an exploratory study, a constructivist philosophy underpinned the descriptive qualitative research approach used (Caelli et al., 2003).

| Sample
The sample was drawn from the population of young people living under the protection of Norwegian CWS. Nationally, 55,623 young people are under CWS care, with 15,140 of them being living in CWS/foster homes (SSB, 2019). In Norway, the most common arrangements are foster homes (i.e., 11,000 people), supervised apartments (2000 people) and institutional care (1000 people) (SSB, 2019).
This study took place in one of the 356 Norwegian municipalities of around 143,000 residents. We chose it owing to CWS size and ease of access; first, it had to have a sufficient number of young people to allow researchers to recruit a sample that would suffice for study aims. Second, given that this population is hard to access for research, the fact that the first author had previously worked at-and had research contacts in-this municipality served as a facilitator for access. The municipality's child welfare manager granted permission for 207 young people (16-22 years) living under CWS care to be invited for interview. At this age, young people were deemed mature enough to reflect on their personal circumstances and to provide indepth data on the impact of care. We set a lower age limit of 16 as below this age, Norwegian policy requires parental consent for participation. An upper limit of 23 was set as, although young people officially can leave care at 18 years, they are not obliged to until 23. At their own discretion, young people were asked to make contact with the first author if they wished to participate. Twenty-five people volunteered; most were living in foster homes (n = 19), and others were in apartments with supervision (n = 4) or institutional care (n = 2).

| Interviews
Interviews were conducted by the first author, who has professional expertise in children's social work. Participants underwent semistructured interviews about their sibling experience during the analysed period. The word 'Sibling' is a biological, legal, cultural and/or relational term (Waid, 2014), and people's definition of a 'real' sibling vary. The interviews allowed for participants to talk about relationships that were meaningful to them and decide for themselves what they defined as a sibling relationship (Hegar & Rosenthal, 2011).
Most talked about their biological siblings, albeit some mentioned step-siblings. Drawing on the social network theory, interviews explored the structure and quality of the ties between the siblings in participants' family network. We paid particular attention to what Borgatti et al. (2009) refers to as the affective nature of these ties, through which resources of love and support might flow. Interviews started with an overview of the structural features of the network: number of siblings in the family, birth order, year of removal from family and sibling age and gender. To obtain in-depth data on participants' reflections about the affective qualities and dynamics of sibling relationships over time (i.e., before and after removal) and space (from the biological home to the CWS environment), participants-together with the interviewer-drew maps of their personal sibling network ( Figure 1). These maps were based on Samuelsson et al. (1996)'s study; specifically, the inner most circle represents participants; the concentric circles denote decreasing levels of closeness or affection between siblings in the network, and a quadrant is imposed on these concentric circles. These quadrants represent living with or separately from the sibling and whether participants are referring to the relationship before or after sibling removal when admitted to CWS care. Participants were asked to indicate the place on the diagram that best described their sibling relationship; they then justified the choice.
Interview also explored the impact of these relationships on participants' well-being. Interviews lasted from 45 min to 2 h, were audio recorded, and transcribed verbatim-with participants' informed consent.

| Analysis
Interviews were analysed concomitantly to data collection to explore emerging themes in future interviews. The first author (W.H.) anonymized the interview tapes, transcripts, and quotations. First, she divided the data into the following two data sets: those on sibling Helping his brother, the task becomes too big The task became too congested, negatively affecting own mental health 'Yes, so they gave me a lot of joy. … (I)like to see that they mastered things, that they feel good, that they feel that become involved in something and manage it even they had a hard time. I help them to have fun, I made them smiled. It meant a lot to me'.

Helps siblings and is recognized for the work
The task provides opportunities to experience competence and mastery Adaptive parentification 'It gave me that feeling…., not that I'm doing things so well but a feeling that I'm now doing something right. Now I'm doing something positive for someone'.

Positive emotional feelings
The task of taking care of siblings provides joy and encouragement relationship in the biological home and those on sibling relationships after admission to CWS care. Then she conducted an inductive thematic analysis (Gibbs, 2007;Graneheim & Lundman, 2004). This involved familiarization, identification of meaning units and the assigning of a brief heading to each meaning unit (which summarized the connotation of each meaning unit) in an open coding process. These codes were then grouped into higher level categories, and the first author endeavoured to clearly rationalize the membership of each code by constantly comparing them. Themes and subthemes were constructed from the categories that appeared during the process of abstraction. To confirm the trustworthiness of the categorization and abstraction process (Shenton, 2004), conducted by the first author, the analysis was checked and discussed with the second author. Table 1 shows an illustration of the analytical process. The first author, whom is a native Norwegian speaker, translated the quotations into English, which were then checked by the second author, who is a native English speaker. We used QSR NVivo 12 to manage the data.

| Sample description
All 25 participants were young people (age range of 16-22 years, average age 18.3). In total, participants had 86 siblings. There were nine boys and 16 girls, and all were removed from their biological families and placed in foster homes or CWS institutions (e.g., youth homes or apartments). Four participants were born outside of Norway, and two were children of immigrant parents. Participants had one to seven siblings (Table 2). Although all participants were removed from their biological families by the Norwegian CWS, the ages at which this occurred varied (Table 3). Most participants were separated from their siblings during some period along the transition to CWS care (n = 17), but removal circumstances and coplacement were complex and highly variable among participants (Table 4).
Two overarching themes arose from the analysis, each comprising of three and four themes respectively and summarized as follows: Sibling relationship while still living with the biological family Child entered care together with a sibling for a short time (coplaced) but then the child was moved alone into a separate care setting (n = 4).
Child entered care where sibling already lived. They then were separated from the sibling after several years together (n = 1).
The child entered care alone and was separated from other siblings. These siblings were either moved to another care setting (23), or/and remained with the birth family (n = 10).
The child entered care as the only child from the biological family. After a while they were joined by other siblings from the biological home (n = 1).
The child entered care as the other sibling was already adult (n = 1).
Living in care with one or more siblings (from birth home) n = 8 The child entered care at the same time as sibling and had an intact sibling placement (coplaced) (n = 1).
Child entered care with one of their siblings but was split from other siblings who entered other care settings or stayed at home with the birth family (coplaced and split) (n = 5).
Child entered care where sibling already stayed but were separated from other siblings who remained in the birth family (n = 1).
Child entered the care of a grown-up sibling, while other siblings remain in birth family (n = 1).
alliance formation between siblings, a process of parentification/sibling caretaking or a relationship that was conflictual or potentially abusive: • • Parentification (sibling caretaking) Other participants described asymmetrical sibling relationships in their biological home; they were either caregivers for or being cared for by their siblings. The direction of these relationships was not consistent; a sibling was sometimes a caregiver, and other times a care recipient.
One participant talked about the relationship as a care task: giving and experiencing physical/emotional consequences, relationships were described as a destructive parentification process. Generally, this sibling caretaking pattern, adaptive or destructive, was characterized by a lack of rivalry, quarrels, conflicts and fun, all of which are often seen in more common/horizontal sibling relationships.
Sibling caregivers only talked about engaging in fun activities with siblings (e.g., playing outdoors) when they were in weekend homes, a situation in which adults were taking care of them.
• Conflict or abuse between siblings Participants also reported some strong sibling conflict/abuse in the biological home. The conflicts were often severe enough to negatively influence siblings' normal daily activities (e.g., being with friends, engaging in school and homework, eating and sleeping). Sibling conflicts created ongoing tension in the home that was difficult to cope with, evoking long-term anxiety in affected siblings. Participants perceived these sibling conflicts as different from normal sibling conflicts, having a devastating impact on their well-being. One described the following: It wasn't just siblings arguing; it was fierce arguing-it was bullying (Girl,19).
Conflicts sometimes included parents and alliances formed between different family members; these sometimes led to violence: one girl reported sitting close to her dog, as protection against an abusive brother. Some participants reported psychological abuse/by siblings alone or together with parents. One explained that when sibling conflict began, her mentally ill mother would lock herself in the bedroom; this led to a chaotic home, conflict escalation and unclear, unstable sibling relationships. Participants also reported conflict when family members used each other for emotional regulation: My brother could not be angry at my parents because they could not handle it, so he reacted against me (Girl, 18).
These conflicting siblings again did not discuss poor parental care nor the sibling relationship. They seemingly only reacted against one another.
3.3 | Pathways from the past to current sibling relationships when in care There were several differing onsets for such close relationships; some reported no major sibling relationship changes. They talked of strong alliances in the biological home that remained strong after admission to CWS care (from alliance to close and supportive relationships, arrow 3, Figure 2).
Other participants reported past conflictual relationships that eventually became close and supportive (from conflictual to close and supportive relationship, arrow 1, Figure 2). These participants developed a close sibling relationship after being separated from their siblings. Living apart allowed for individual development in different homes and the space to build stronger and reciprocal sibling relationships: After I moved out, he started to take it out on dad, so now we have got a good relationship (Girl, 18).
Although separation seemed desirable for some, other partici- close and supportive (From no previous experience/memory of the sibling to close and supportive, arrow 4, Figure 2).
• Sibling relationship in care is in conflict Some participants described their current sibling relationships as conflictual and destructive. They were bullied or undermined by siblings, causing them pain. These conflictual relationships arose when siblings who were left with the family became resentful of the new opportunities given to the relocated sibling, or when coplaced siblings disagreed how to adapt to the foster home. There was little mention of support, empathy or love between these siblings. Some felt they should have good sibling relationships, but that conflict was too intense for this to be achieved. As with the pathways to strong, supportive relationships, pathways to conflict varied. For some young people, the original relationship was already conflictual. But equally, the relationship could have begun as a form of parentification or have been non-existent.
For some, family trauma and jealousy in the past (e.g., the damage of living with drug addicted parents) had proven too much for their relationship and was never repaired (Conflict to conflict, arrow 11, Figure 2).
Other young people, who had been in parentification relationships in the past, currently felt they had failed to live up to sibling expectations leading to poor relationships today (Parentification to conflict, arrow 9, Figure 2). Some, with no memory of the past relationship, were unable to build new sibling relationships and conflict ensued (No experience to Conflict, arrow 10, Figure 2).
Siblings conflict in the care setting continued or developed whether siblings were separated or not: for some being kept together meant they did not get the distance from each other required to save the relationship. For others, providing distance through separation still did not resolve their conflict and in fact, exacerbated the situation being sustained through phone calls, social media or meetings: If you have strong conflicts with friends, you can end the relationships. But, it is not possible to end sibling relationships because they are siblings (Girl, 18).
• Sibling relationship in care is distant Some participants described their current relationships as distant, that is, neither in conflict or strong/supportive but instead was 'on hold'.
Siblings described needing space for themselves to re-evaluate their expectations of their sibling relationships and that there was currently little contact. Some initially parentification relationships developed in this way, siblings wanting the distance provided by separation (Parentification to Distance, arrow 7, Figure 2). For example, one boy, engaged in parentification relationships with his siblings, described needing distance to develop as a person.
Distant sibling relationships also developed from relationships that had been alliances in the birth family (Alliance to Distance, arrow 6, Figure 2), with the new distance between the siblings being a release from these intense alliances. They have found living with siblings who had shared the same experiences of suffering and neglect as uncomfortable, especially if they knew the siblings were still struggling, and they could do nothing about this. For some, the distance was a welcome break from previously conflictual sibling relationships (Conflict to Distance, arrow 8, Figure 2 • Sibling relationship in care is broken In this theme, siblings report no contact with each other now they are in care. Some had some contact after going into care but not anymore. Some had never established a relationship because of large age gaps or living in different birth families from birth (e.g., siblings from different parents). For some young people, this cessation of contact is deliberate. They do not phone siblings or make contact via social media and avoid places where they might meet. This is an act of selfpreservation. These broken relationships arose from a range of beginnings: for some, the relationship in the home had been strong conflictual (Conflict to Broken, arrow 12, Figure 2), physically or psychologically violent leading to a complete relationship break down.
Memories are so traumatic that young people need to break all contact in order to cope. One girl was abused by both parents and her brother. Another girl was used by the family as a scapegoat for family.
Relationship breakdown also occurred because other siblings had serious problems, often related to drug use or mental health issues. It can be too painful or risky for the child to sustain these relationships and they fear the sibling will bring them down with them.
Parentification relationships also break down (Parentification to Broken, arrow 13, Figure 2). One girl had an older sister, who cared of her when they lived together with a mentally ill mother. They were dependent on each other but were also jealous of each other. There was no adult to help them manage and reshape their relationship and no contact at all seemed the only way forward.
A final pathway to a broken sibling relationship were those where no initial relationship (No Experience to Broken, Arrow 14, Figure 2).
Here, young people spoke of older siblings that they only knew the name of or had never, or seldom, met in the past. They did not see the point of establishing a relationship with these siblings.
I do not think I can have an equal relationship with the two elders anyway, that chance has somehow gone (Girl,19).
All the relationships that are broken today were either young people who had been split by Child Welfare when they were moved from birth family or who had grown up in another separately family.

| DISCUSSION
Social networks, the quality of ties and the flow of resources within them are vital in our lives, and siblings play a central role in these networks-for good or bad (Gustavsson & Maceachron, 2010;Rast & Rast, 2014;Whelan, 2003;Wojciak, 2016;Wojciak et al., 2013).
Young people in care in this study place an emphasis on the significance of these sibling relationships for them. They expend much energy on constructing/reconstructing or destroying these. For some, it is the most important relationship in their lives, and they spend much time with, or thinking about, siblings. Constructing the sibling relationship is an ongoing process, and removal from the biological home is a major transitional event, as is starting school, developing close relationships and puberty (Conger et al., 2009). Even when sibling relationships seem destructive, these are central to the social network of young people in care, as it is for any young person (Sting, 2013). On the one hand, ongoing conflicts become a major focus for everyday life, and if unresolved, relationships can become distant, broken or conflictual. On the other hand, young people separated from siblings, but who still work hard to keep a close and supportive relationship with them, are also struggling. Young people describe both situations as exhausting, making it hard for them to live ordinary lives and compromising mental health. Managing the sibling relationship appears to have critical impact on their well-being now and in their future. If sibling relationships are thought to impact on young people's lives more than the parental relationship (Gustavsson & Maceachron, 2010), this may be especially true for young people in care.
Young people in this study describe sibling kinship ties in the biological family, in variable ways: siblings may act as parents or as allies but relationships may also be conflictual and abusive. For some, there is no direct contact with the siblings in their wider social network at this time. However, these initial sibling relationships are not set in stone but are dynamic features of the siblings' social network that reshape when young people leave the birth family and move into care.
This reshaping of sibling relationships is an ongoing natural process for all young people as they mature, but for those in care, there are added challenges because of the removal from a vulnerable family situation and potential separation from one or more of their siblings.
Some are struggling for reconciliation to improve the relationship while others take care of themselves by distancing themselves or breaking contact altogether. These dynamic features of the sibling relationships, means that initial status of the relationship in the biological home does not necessarily dictate the quality of the relationships in care. For example, relationships with strong conflict in the past can move to supportive and good relationships in current situations and vice versa.
The reshaping of sibling relationships that occurs during the transition into care is a complex process. This is reflected in the multiple pathways presented in Figure 2  Young people must reshape these relationships themselves as best they can. It is possible that social workers, or foster carers, prioritize the parent-child relationship, paying less attention to the sibling relationship. These professionals should therefore be encouraged to monitor the sibling, as well as parental, relationships after removal to understand each young person's experiences of these. They need to support them reshape these relationships in the best interest of all in the sibling group, both if they are separated from each other but also if they are kept together. Help may be particularly required to build sibling relationships when children are young, when they depend most on an adult to build and maintain these relationships in such a way that benefits them (Drapeau et al., 2000;Richardson et al., 2017).
Social workers have key decisions to make on whether to separate siblings or not when moving a person into care. Some researchers advocate for coplacement of siblings (Hegar, 1988;Herrick & Piccus, 2005). Others point out that there is little empirical support for this (James et al., 2008;Linares et al., 2007). Our research suggests there is no definitive answer and that it is hard to predict the outcomes of a coplacement. Our research finds cases that supports research that some children do as well when placed together (Albert & King, 2008;Hegar, 2005;Hegar & Rosenthal, 2011;James et al., 2008;Jones, 2016;Wojciak et al., 2013). Coplacement can help siblings bond and minimizes the trauma children experience when separated from parents (Albert & King, 2008;Wojciak et al., 2013).
Siblings feel more emotionally supported (Hegar & Rosenthal, 2011) and children report higher well-being than those in care alone (Davidson-Arad & Klein, 2011). Coplacement has been associated with fewer emotional and behavioural problems (Herrick & Piccus, 2005), less loneliness and depression (Milevsky, 2005), less placement disruptions (Leathers, 2005) and can speed up the reunification processes (Albert & King, 2008). On the other hand, our research also found there were some young people for whom separation had advantages. As in other studies (James et al., 2008;Jenkins & Dunn, 2009;Linares, 2006;Richardson et al., 2017;Ryan, 2002), not all children had close sibling relationships, and distance between siblings may be beneficial in some cases especially if sibling bullying and violence are prevalent. In our findings, some children specifically ask for distance even though they had had close sibling relationships in the past: they needed 'space to find themselves' or had found it too hard to be constantly reminded of the trauma they had lived under together.
Our findings also show that, while the data are clearly categorized into what young people remembered of their relationships in the biological family and how they saw them now that they were in care, the pathways between these time points are highly variable. It is premature therefore from this analysis to draw conclusions on how the circumstances of removal (together or separate placements) has impacted on these multiple pathways described in Figure 2. What our study contributes however is insight into the complexity of the context and the dimensions that make it up. Social workers and foster carers may desire standardized approaches to sibling coplacement.
However, our analysis suggests that attempts to categorize the current state of sibling relationship by form of sibling coplacement may oversimplify a complex phenomenon. It may be that there is no one-size-fits-all solution for the form of sibling placement that should be followed by social workers and that each young person, and the sibling, be treated as an individual case. In line with Drapeau et al. (2000), the decision on whether to separate or coplace siblings is more complex than simply a yes or no. Instead, an individual assessment of each case is required. Social workers should take into account the type of sibling relationship in the biological home, but understand that sibling relationships that then develops in care are not a forgone conclusion. The type of placement that is best suited to the young person is likely to vary widely from one case to another. This complexity is illustrated in the pathways diagram ( Figure 2) showing multiple and crisscrossing lines between themes connecting the nature of the sibling relationship before and after removal. The transition between the home and care, and its impact on sibling relationship, is far from a linear and discrete process.

| LIMITATIONS AND THE WAY FORWARD
This is an exploratory study presenting the range and depth of participants' views. The sample descriptions (Tables 2-4) of the specific circumstances of the participants assure some transferability of the findings to other national and international settings. However, as a qualitative study, the sample size is characteristically small, and future quantitative research is now required to test some of the hypotheses created through the study. Key here is to explore in larger samples the prevalence/distribution of each pathway in the care population. In this small sample, no pattern was immediately obvious in terms of placement type largely because of the many varied characteristics of each participant themselves and their varied relationships/transition pathways with each of their siblings respectively. These dimensions however may now serve as the substantive content required for survey tools and quantitative multilevel analysis follow-up studies in which participants could be asked to name each sibling, whether they are separated or not from this sibling and to categorize the relationship with this named sibling in terms of before (parentification, none, alliance and conflict) and after being taken into care (close, conflict, distant and broken). This is now required to more definitively determine the impact of sibling coplacement. Larger scale surveys of this kind could also test if significant relationships can be detected between placement type (and other environmental factors including participant attributes of gender and size of sibling group) and each of 14 pathways described in our current study. These analyses will shed light on reasons why in some cases separation of siblings strengthens some sibling relationships but not others. These studies may also be able to control for some of these multiple environmental factors, that are likely to be influencing the sibling relationship, in addition to placement type.
Qualitatively, the interviews have also told us little of how exactly the processes of construction, reconstruction and destruction of the sibling relationship actually took place along the pathways highlighted in Figure 2. Apart from phone and social media, young people do not elaborate on how relationships are maintained or changed. We suggest this reflects a gap in competence in these young people. The paper recommends that, in the absence of children being able to articulate strategies of how to build positive sibling relationships, it is for social workers/foster carers to help them develop these. Currently, and from childrens' own reports, these adults do not yet provide them this support. Future research is required to explore if indeed social workers and foster carers do offer this support and, if so, how it is done. This could include investigating social workers/foster carer views of the benefits of developing in children various forms of communication style to use with their siblings, such as social media, but also helping them negotiate its dangers.
The view of the social worker/foster carer is also worth exploring as an alternative perspective to that of the young person. Not because the young person's report of their own experience is of lesser value, but as a different subjective view of reality that triangulates with that of the young person. It could maximize the chances of understanding the conditions needed to maximize the young person's well-being.

| CONCLUSION
This paper aimed to explore young people's perceptions of how sibling relationships change when they move from the biological family into care. It shows sibling relationships to be important for young people and describes the quality of sibling ties when in the biological family (parentification, close, conflictual or nonexistent) and then the quality of these social ties when in care (broken, conflictual, close or distant). The study has uncovered multiple pathways in which the quality of these kinship ties change as the young person moves from the family into care. This suggests firstly the complexity and bespoke nature of this transition but also the possibility that an appropriate sibling relationship in care is possible regardless of the initial relationship in the biological home.
There is a need for a bespoke solution to the needs and circumstances of each sibling pair, that is difficult to predict or standardize, if the ideal sibling relationship for the young person is to be reached.
We recommend that social workers, together with foster careers, place explicit focus on the dynamic construction of the sibling relationship when a child is removed from the home. Any decision on placement should be made on a person centred, flexible approach that allows for the changes in this dynamic relationship as best suits the child. Better strategies and tools to managing the reconstruction of the sibling relationships need to be explored and applied.
