The eat, wake, sleep cycle is a routine that you follow with your baby throughout the day. Their day is a repetition of eating, then having awake time, then sleeping. The idea is that you aren't creating a sleep crutch by feeding your baby to sleep. Rather, they learn to take full feedings when they wake up, and they learn to put themselves to sleep without needing to nurse or have a bottle to soothe. Your baby ends up eating only when they are truly hungry, and not simply for comfort. Read about the eat, wake, sleep cycle here.
