ABSTRACT: Of 100 new mothers self-selected for study, 87 percent breastfed for at least 2 weeks, and a mean of 6.8 months. Upon weaning, 29 percent of infants were given cow's milk and the remainder were fed formula. Breastfeeding mothers introduced solid foods later, used more homemade baby foods, were more likely to have attended prenatal classes, and were more receptive to infant feeding advice from friends and classes, while formula-feeding mothers preferred the advice of their pediatricians.
