No. Waiting longer between feedings actually will make your body produce less milk. An empty breast makes milk more quickly, so the more frequently you feed your baby (or empty your breasts with a pump), the more milk your body will produce. It isn't unusual for newborns to want to feed as often as every hour, so feed baby as often as she shows signs of hunger (like rooting or sucking). Breastfeeding is a true supply-and-demand affair: The more you feed, the more milk your body makes.
