Start from the time they wake up and count back the sleep they need. Pick their age and wake-up time.
Lights out between 7:00 and 8:00 pm.
Lights-out windows for three common wake-up times. Lean toward the earlier end if they wake up tired or skipped a nap. For 1 to 3 year olds, this is night sleep with a nap on top.

Sleep windows use the American Academy of Sleep Medicine's recommended hours by age, which the American Academy of Pediatrics endorses. Every kid is a little different. If you're worried about how your child sleeps, ask their pediatrician.
