Naps are disappearing in this age range but there may be a few naps per week. Another variable is that here are more scheduled activities but not nesessarily every day or at the same time every day. Children have more viral infectons in this age range and some may disrupt sleep. Also some of these children have baby siblings that naturally may disrupt the sleep routines of the older child. If the child has an older sibling, the older child's scheduled activiites might make naps or reasonably early bedtimes problematic for the 3-5-year-old. Can you think of other major variables that affect sleep in this age range?
Given these variables, how do you accomplish a reasonably early bedime for the 3-5-year-old child? When is the bedtime too late?
