Two Naps vs. One Nap
When toddlers drop to a single nap — and how to know it's time.
Quick answer
Most toddlers transition from two naps to one sometime between about 15 and 18 months, though the range is wide. The signs it's time: your child regularly fights the morning or afternoon nap, takes a long time to fall asleep, or the second nap pushes bedtime too late. The usual fix is to gradually push the morning nap later until it becomes a single, longer midday nap — expect a bumpy week or two of adjustment.
Two naps
A morning and an afternoon nap — typical for younger toddlers and babies. More total day sleep, split into two windows.
One nap
A single, longer midday nap — typical once a child resists two. Simpler schedule, better-aligned with preschool and family routines.

| Total day sleep | Slightly more | Slightly less, consolidated |
| Transition | — | Push the morning nap later over 1–2 weeks |
| Watch for | Short/skipped naps signaling readiness | Overtiredness during the switch |

Frequently asked questions
What age do toddlers drop to one nap?
Most commonly between 15 and 18 months, but some are ready earlier and some later. Readiness signs matter more than the exact age.
How do I transition from two naps to one?
Gradually push the morning nap 15–30 minutes later every few days until it lands around midday and becomes one longer nap. An earlier bedtime helps during the adjustment.
Is it normal for sleep to get worse during the switch?
Yes — a week or two of overtiredness, early wake-ups, or rough evenings is common. Consistency and a slightly earlier bedtime usually settle it.
What if some days need two naps and some need one?
That's normal during the transition. Stay flexible, offer a second short nap or an early bedtime on rough days, and let it settle over a couple of weeks.
