Nap transitions: when thewhole schedule shifts.
The schedule finally worked. You knew exactly when naps happened, when bedtime landed, what the day looked like. And then, seemingly overnight, the third nap became a fight, bedtime drifted, and the whole structure started wobbling.
That's usually not a regression. It's a transition — your child's sleep needs are changing underneath the schedule you built.
What's actually happening
Babies drop naps on a fairly predictable arc: from many naps down to three, three to two (often somewhere around seven to nine months), two to one (often somewhere around fifteen to eighteen months). Each drop is the same story: wake windows lengthen, the last nap stops fitting, and the day needs reorganizing.
The wobble is real but temporary. The mistake is usually not the transition — it's changing five things at once in response to it.
Real transition vs. rough week
The refused nap keeps happening — not twice, but most days for a week or more.
When they skip it, they make it to bedtime in reasonable shape.
Bedtime is drifting later, or night sleep is shortening.
The remaining naps are solid — it's the schedule edges that are failing, not sleep itself.
How to move through it
Shift gradually: stretch wake windows by small amounts rather than deleting a nap overnight. Use an earlier bedtime as the pressure valve during the transition weeks — it prevents the overtired spiral that makes everything look worse than it is.
And expect a messy middle: some days on the old schedule, some on the new. That's the transition working, not failing.
When it's worth a conversation
If the transition has been 'happening' for a month and nothing has settled, there's usually a specific snag — timing, bedtime, or how nights are interacting with days. A short look at the whole picture usually finds it.
A few things parents ask me
How long does a nap transition take?
Usually one to three weeks of wobble before the new rhythm holds. Longer than that usually means something specific is snagging it — which is findable.
Should I drop the nap cold turkey?
Rarely. Gradual shifts with an earlier bedtime as the safety valve get you there with far less overtiredness. Cold turkey works for some toddlers at the 2-to-1, but even then, early bedtime does the heavy lifting.
Tell me what happened last night.
You don’t need to have any of this figured out before we talk. I’ll ask some questions, we’ll look at what you’ve already tried, and I’ll tell you what I notice. Then you decide.
