Nap Time for Toddlers
In the months after your baby's first birthday, he will probably still take two naps a day to meet all of his sleep needs. During these months, he will clearly reach his limit after a stretch of four to five hours of wakefulness. If he stays up longer than this, your child will become whiny, belligerent, and generally miserable. So if your toddler wakes at six, you'll probably need to put him down for his morning nap between ten and eleven.
