For starters, you don't really want to sleep like a baby . Babies' sleep, especially in the early months, is typically full of interruptions because a baby's sleep cycle is shorter than an adult's. Babies have twice as many light sleep cycles as adults, more light sleep than deep sleep, and their overall sleep cycles are shorter. Often, interrupted sleep for all.
Babies are likely to wake up frequently as they move from deep to light sleep in any sleep cycle.
In the early months, babies need help falling asleep and getting back to sleep. And often, you'll have to spend a lot of time helping an infant get into a deep enough sleep so you can lay her down. The baby was still in light sleep when you let her go. In these early days of an infant's life, recommends Dr. William Sears, in The Baby Book , you should wait until your baby is in a deep sleep before laying her down. Gently pick up an arm or leg, and if it flops back down and your baby doesn't jerk it, or jerk awake, you've got a deeply sleeping baby.
