What does a 15 month old sleep schedule look like, from 2 naps to 1?

This is the age of the last big nap transition, and it takes weeks. So two schedules side by side isn't sloppiness here; it's reality.

While two naps still work

A toddler's day then looks like this.

Kyra's test is simple: if the nights go well and your little one wakes up around 6:30 am, there's no reason yet to change anything. Bedtime is between 7:00 and 7:30 pm.

The sign that one nap is coming

Your little one refuses the morning nap. Not once, but consistently: around 9:30 am, they simply don't want to sleep anymore.

That's the moment to start, not the calendar.

The transition from 2 naps to 1, in four steps

Step 1. Push the morning nap later. Step by step, from 9:30 am to 10:30, 11:00, 11:30 and finally 12:00. Not all at once.

Step 2. Turn it into an afternoon nap. The goal is a start time between 12:30 and 1:00 pm, with a total sleep of 2 to 2.5 hours.

Step 3. Keep bedtime earlier for now. On hard days, bedtime 30 to 60 minutes earlier. This is the step that gets skipped most often, and it's the one that makes the transition bearable.

Step 4. Expect a transition period. Some days one nap, other days still two. That's normal, and it takes weeks.

Kyra sums it up in a few words: follow your child, not the calendar.

When it suddenly becomes 5 am

Early waking is part of this phase and is almost always a result of how the day is set up: bedtime too late, overtiredness, or too little daytime sleep. See waking too early.

How long your little one can stay awake at this age is in wake windows for toddlers. What comes after, with one afternoon nap, is in the toddler sleep schedule.
