““in the early months enter sleep through an initial period of light sleep lasting around twenty minutes. Then they gradually enter deep sleep, from which they are difficult to arouse. If you try to rush by putting baby down during this initial light sleep period, he will usually awaken. This fact of infant sleep accounts for the difficult-to-settle baby who “has to be fully asleep before I can put him down.” In later months many babies can enter deep sleep more quickly without first going through light sleep. Learn to recognize your baby’s sleep stages. During deep sleep you can move a sleeping baby from car seat to bed without baby awakening.””
