18-month-old wake windows

By eighteen months, one midday nap is commonly the clearest rhythm, with a substantial final wake window before bed.

Example, not a fixed schedule

The actual day depends on the morning wake time, how naps unfold and whether the baby is transitioning between rhythms. Use ranges flexibly and avoid forcing sleep solely because a clock time has arrived.

How long should the nap be?

Nap duration varies by nap and by child. Lulla gives a flexible suggested range inside the calculator rather than one compulsory duration. A late bridging nap is usually shorter than a main midday nap.
