When Do Babies Transition to One Nap?
There’s a moment in early toddlerhood that feels deceptively small, but it really does change everything. It starts quietly. Your baby refuses their second nap one afternoon, and you think to yourself, hmm that’s strange.
The next day, they skip it again. You try rocking, singing, stroller walks, a car ride, a dark room. Nothing works. By dinner, they’re teetering between giggles and meltdowns, a mix of tired and wired.
Welcome to the in-between. That long, confusing stretch when babies begin to drop from two naps to one. It’s one of the biggest transitions of the first two years, and it doesn’t happen overnight.
For weeks, sometimes even months, your baby’s sleep will wobble between what was and what’s next. Like most changes in babyhood, it unfolds in waves: some days smooth and golden, others just a little messy.
The Typical Timeline (and Why It’s Never Typical)
Most babies make this shift between twelve and eighteen months. Some are ready closer to eleven, others hold onto two naps into the toddler years. There’s truly, honestly, no “right” time. Only readiness, and that can’t be forced or scheduled.
You’ll start to notice longer awake times before the first nap, or long stretches of chatting and rolling before falling asleep. The second nap begins creeping later and later, overlapping bedtime. That’s your sign that the balance between sleep and wake time is changing, not that something is wrong.
This stage is less about “fixing” naps and more about learning your baby’s evolving rhythm.
Understanding Undertiredness (Not Overtiredness)
You’ll often hear warnings about overtiredness causing sleep problems, but in reality, most babies struggle more when they’re undertired.
An undertired baby simply isn’t ready for sleep yet. They might seem calm or happy, but when put down too early, their body doesn’t have enough sleep pressure built up. That can lead to long settling times, false starts at bedtime, or early morning wake-ups.
Overtiredness, on the other hand, tends to show up more during awake time, crankiness, clinginess, short attention spans, but it rarely ruins sleep itself. Babies can still sleep well after a busy day if the timing aligns with their needs.
So rather than rushing naps or pushing bedtime earlier, focus on balanced wake windows. Watch your baby’s cues, engagement, eye rubs, or zoning out, and adjust slowly. Their circadian rhythm is maturing; it just needs consistent timing and light exposure to settle.
The Art of the Transition
Think of this shift not as a switch, but a dance. You’ll lead for a while, then follow, then find your rhythm together.
Some days, your little one will sail through the morning and happily nap around midday. Other days, they’ll need a short “bridge nap”, just ten or fifteen minutes in the car or stroller to smooth the stretch. And occasionally, they’ll conk out at dinner. It’s all normal.
Avoid making the bedtime too early unless your child has unusually high sleep needs. In most cases, an early bedtime can backfire, leading to false starts, split nights, or early rising. Instead, aim for a balanced day that builds enough sleep pressure before night.
The key is to give their body time to adjust. Over a few weeks, naps lengthen, mornings stretch, and the whole schedule starts to settle.
What Helps (and What Doesn’t)
The best support during this phase is calm consistency.
Push the morning nap gradually, by ten or fifteen minutes every few days, until it naturally lands in the middle of the day. Keep the sleep environment familiar and low-stimulation.
Avoid rushing the process or over-correcting. A skipped nap here or there isn’t a setback; it’s practice. Offer quiet time instead of forcing sleep, and focus on patterns over perfection.
And remember, there’s no such thing as a “restorative nap.” Sleep is sleep. Whether it happens in the crib, stroller, or your arms, your baby’s body knows how to get what it needs.
Finding the Right Rhythm for Your Baby
Every baby has their own little internal rhythm, and the goal during this stage isn’t to chase perfect timing, it’s simply to discover a pattern that fits your little one. Some babies thrive with slightly longer wake windows, others still need short recharge breaks to stay happy through the day.
If your baby’s first nap starts drifting too late, that’s your cue they’re ready for a longer stretch of awake time. If they’re resisting the nap entirely, it may be time to shift it closer to midday. A nap around five hours after morning wake-up works beautifully for many toddlers, but every child is different.
The trick is to experiment slowly. Try adjusting nap start times by ten to fifteen minutes and observe how bedtime feels. Is your little one playful or cranky? Falling asleep easily or wide awake at 8 p.m.? These small patterns tell you everything you need to know.
And don’t stress if your baby naps on the go. A contact nap, stroller nap, or car snooze is just as valid as crib sleep... what matters most is that they’re getting enough rest across the day, not where it happens.
When Routines Get Off Track
If your baby’s schedule goes sideways after travel or holidays, don’t stress. Sleep routines are flexible by design. It usually takes just a few days of consistency to find balance again.

The Other Side of the Shift
When the transition finally settles, you’ll both feel the difference. One nap means more time for outings, play, or rest, and more routine in your day.
This milestone often feels emotional because it represents change, not just for your baby, but for you, too. Each phase asks you to release what used to work and trust what comes next.
If you’re in that messy middle of the nap transition, remember: it’s temporary. Whether your baby is just starting to transition to one nap or you’re helping an overtired infant find their rhythm again, consistency and calm always win out.
