The 2 to 1 Nap Transition: When and How to Do It

By Paola Mendoza, Certified Pediatric Sleep Consultant (CPSM) · Last updated September 2026

Quick answer: Most toddlers drop from 2 naps to 1 between 13 and 18 months, often around 15 months. The transition goes best when it happens gradually over a few weeks, with the nap settling around midday and an earlier bedtime while your toddler adjusts.

It's 2:30 p.m. and you've been in the nursery for 40 minutes. Your toddler is chatting, singing and throwing the pacifier over the rail. This is often the first sign the 2 to 1 nap transition is coming. The trick is knowing whether it's time, or just a phase.

When do toddlers drop to one nap?

Most toddlers drop to one nap between 13 and 18 months. Many parents try it at 12 months because their baby suddenly fights a nap, and that's usually too early. Around the first birthday, many babies go through a short patch of nap refusal that passes on its own. Under 13 months, keep offering 2 naps.

What are the signs my toddler is ready for one nap?

Look for a pattern that lasts at least 2 weeks. If you see two or three of these most days, you're probably ready:

Signs it is time

• Skips or takes forever for one nap for 2+ weeks
• Naps shrink to 30 to 45 minutes
• Second nap pushes bedtime past 8 p.m.
• Handles 4+ hour wake windows well

Signs it is a phase

• Under 13 months
• Only a few bad days
• Cranky and overtired on 1 nap
• Nights fall apart when you try it

How do I transition from 2 naps to 1?

Gradually. Dropping the morning nap overnight usually means an overtired toddler and a rough month. The gentlest transitions shift the day slowly over a few weeks until one nap lands in the middle of the day. How fast to move depends on your toddler’s sleep, their temperament and daycare, which is why the pace is different for every family.

Why does my toddler need an earlier bedtime during the transition?

This is the part parents skip, and it's the most important. One nap means a long afternoon, and a toddler who isn't used to it will be running on fumes. A sample day during the transition:

• 6:45 a.m.: wake up

• 12:00 to 2:30 p.m.: nap

• 6:15 p.m.: bedtime routine

• 6:30 p.m.: asleep

Once your toddler adjusts, usually after 2 to 4 weeks, bedtime can move back to 7:00 or 7:30 p.m.

What if the one nap is short?

A short nap is really common in the first weeks, often waking at the 45 minute mark.

• Give them 10 to 15 minutes to see if they fall back asleep

• On rough days, a 20 minute car or stroller nap in the late afternoon is fine as a bridge

• Move bedtime earlier on any day with a short nap

This is a transition, not a test. Some days will look like 2 naps again, and that's okay.

What if daycare moves my toddler to one nap early?

Many centers move kids to one nap at 12 or 13 months. If that's your situation, the early bedtime becomes your best friend, and weekends can be a little more flexible while your toddler's body catches up.
