The
bedtime window goes a bit
later for kids 15 months to 3 years old: 6 p.m. to 8 p.m. And for preschoolers 3 years to 5 years old, Nicole
suggests a
bedtime between 7 p.m. and 8:30 p.m. Assuming it takes your child roughly 10 minutes to fall asleep, you'll want to begin the routine at an appropriate time in advance of your child's
bedtime.
