At least three hours should elapse between the end of an afternoon nap and bedtime. Pediatrician Richard Ferber, founder of the Center for Pediatric Sleep Disorders at Boston Children's Hospital, says your child may give up his morning nap by age 2. Don't let your child sleep past 3, or you may have a harder time getting her to bed at night.
William Sears and his family (he and his sons are pediatricians, and his wife is a registered nurse) are known for advocating a gentle, nurturing approach for helping young children settle to sleep.
By the time your little one is four years old, naps will most likely be long forgotten, but in the time between then and now you’ll need your wits about you!
You can tell a nap transition is on the way, because your baby may start to suddenly refuse to sleep when she used to.
Your baby will go from four to five naps per day, down to just one.
So from newborn to 18 months you can expect a lot of changes to your routine.
As with most other sleep issues, consistency on your part is essential.
Newborns and younger babies aside, older babies should have a pretty regular nap schedule that you can keep a track of.Between 4 and 12 months, most babies move to two naps a day (one in the morning and one in the afternoon), each ranging from 20 minutes to three hours. Around the age of 2, most toddlers take a single two-hour nap in the middle of the day, and by the age of 3, some give up naps entirely. He says it also helps to schedule naps for the same time each day and to make sure the napping room is quiet and dark. Try playing soft music, nestling with him in a rocking chair, or lying down with him on a bed.
