At 35 months the default is still one nap of 60–120 minutes around 12:00–1:00 PM, wake windows of 5–6 hours, and a 10–12 hour night from 7:00–8:00 PM, roughly 11–13 hours per day. The 1→0 transition usually lands somewhere between 3 and 5, and the toddlers who drop it earliest tend to be the ones with long, solid nights — a child sleeping 7:00 PM to 6:30 AM has already banked most of their need before lunch.
The mistake to avoid in both directions: dropping a nap that's being refused (control, illness, a new sibling, preschool) and forcing a nap that's genuinely done (which costs you the night). Below is the checklist that separates them, and the quiet-time system that should be in place before the nap goes anywhere — same time, same place, books, 45–60 minutes. Quiet time isn't a consolation prize; it's what keeps the afternoon and the bedtime intact when the sleep itself stops coming.
Signs the nap is ending — and signs it isn't
Genuinely ending (you should see most of these, together, for at least two weeks):
- Takes 30–45 minutes to fall asleep at nap time on most days, without distress — just awake.
- Refuses or doesn't fall asleep 3+ days a week for 2+ weeks.
- On nap days, bedtime pushes past 8:30 PM with an hour of lying awake.
- On skipped days, stays pleasant through to a 7:00–7:30 PM bedtime and sleeps the night through.
Still needs it (any one of these overrides the list above):
- Skipped-nap days end in a 5:00 PM meltdown, car-seat sleep, or an early morning.
- The refusal started with something — illness, a new baby, a new bed, a preschool start.
- Falls asleep quickly when the nap does happen and sleeps 90 minutes or more.
If it's genuinely ending, don't stop cold. The 3-year-old page covers the alternate-days transition; start with quiet time in the nap's slot.
The quiet-time system
Quiet time replaces the nap's function — a mid-day reset for the toddler, a break for you — without requiring sleep. It works because it's a fixed routine, not a suggestion.
- Same time: the old nap slot, 12:30–1:00 PM, every day including weekends.
- Same place: their room, door closed or gated, curtains half-drawn.
- Same materials: a basket of books and 2–3 quiet toys that only come out for quiet time.
- 45–60 minutes, marked by a timer or an OK-to-wake light so the end is visible, not negotiable.
- If they fall asleep, let them — but wake by 2:30–3:00 PM. Sleep during quiet time is the nap telling you it isn't finished.
Introduce it while the nap is still happening on some days, so it's familiar before it's needed. A toddler who's had quiet time for a month treats it as normal; one who meets it the day the nap dies treats it as punishment.
Schedules are averages.
