Breast milk is easily digested, so newborns are hungry often. Frequent feedings helps stimulate your milk production during the first few weeks. By the time your baby is 4-5 months old, he or she probably will nurse 7–9 times a day. In the first few weeks of life, breastfeeding should be "on demand" (when your baby is hungry), which is about every 1-1/2 to 3 hours. As newborns get older, they'll nurse less often, and may have a more predictable schedule. Some might feed every 90 minutes, whereas others might go 2–3 hours between feedings. Newborns should not go more than about 4 hours without feeding, even overnight.
