Many toddlers make the switch to one midday nap of 1½–3 hours around now.

During the 2-to-1 transition, an earlier bedtime covers the gap while the single nap settles.

Make it fit your baby

This schedule is built from the middle of the wake-window range for this age, with windows that lengthen through the day. If your baby fights naps, try stretching each window by 10–15 minutes; if they melt down before naps, shorten them. For a schedule from your baby's exact age, a sleep pressure clock and an AI helper for specific problems, use the baby sleep schedule calculator.

Feeding and sleep go together: see the baby feeding calculator for how much milk to expect at this age.

Safe sleep: the AAP recommends placing babies on their back on a firm, flat, empty surface, in the parents' room for at least the first 6 months.
