Question 1

What is the ideal bedtime for babies by age?

Accepted Answer

Most pediatric sleep specialists recommend bedtimes between 7:00-8:30 PM for babies and toddlers. Earlier bedtimes (7:00-7:30 PM) often suit babies under 6 months and those transitioning naps. Later bedtimes (8:00-8:30 PM) may work for some toddlers. The "right" bedtime is the one that allows your baby to fall asleep within 10-20 minutes and wake up naturally at a reasonable morning time.

Question 2

What should a bedtime routine look like for a baby?

Accepted Answer

A consistent 20-30 minute routine signals to your baby that sleep is coming. A typical routine might include: bath, feeding (breast or bottle), pajamas, dimming lights, a short book or song, and placing baby in the crib drowsy but awake. The most important element is consistency — doing the same routine in the same order every night helps build sleep associations.

Question 3

What are signs that bedtime is too late?

Accepted Answer

Signs of a too-late bedtime include: excessive fussiness or crying in the evening, seeming "wired" or hyperactive before bed, difficulty settling, frequent night waking, and early morning waking (5:00-6:00 AM). Paradoxically, moving bedtime earlier by 15-30 minutes often resolves early waking by reducing the cortisol response to overtiredness.

Question 4

Why does early waking happen and how does bedtime help?

Accepted Answer

Early morning waking (before 6:00 AM) is often caused by overtiredness from too-late bedtimes or insufficient total sleep. The body produces cortisol to compensate for lost sleep, which acts as a stimulant and causes early waking. Moving bedtime 15-30 minutes earlier, and ensuring adequate naps, often resolves early waking within a week.

Question 5

How does the last nap affect bedtime?

Accepted Answer

The gap between the end of the last nap and bedtime (the last awake window) is the most important awake window of the day. For most babies, this is 15-30 minutes longer than earlier awake windows. A last nap ending too close to bedtime (less than 1.5 hours before for older babies) can cause difficulty settling. A last nap ending too early causes overtiredness and too-early bedtime.
