Breastfeeding rates in urban Malaysian mothers are below World Health Organization (WHO) targets. Our prospective survey identified breastfeeding prevalences at 3, 6, and 12 months of 85.5%, 77%, and 60%, respectively. Combined (direct and expressed) breastfeeding significantly sustained longer-term breastfeeding. Efforts should be focused on mothers of Indian ethnicity and on expression after one month postpartum.
