Happy first birthday. If you’re mapping out a 12 month old sleep schedule, you’ve got a toddler who may be cruising, taking first wobbly steps, or babbling real words — and a lot of that new independence shows up at sleep times too. The good news: for most one-year-olds, the schedule itself hasn’t changed much from a few months ago. Two naps and a steady bedtime routine are still doing the heavy lifting. Here’s a realistic hour-by-hour sample, how many naps to expect, wake windows, how to tell if a nap drop is actually near, and how much sleep toddlers this age typically need.
How much does a 12 month old sleep?
On average, a 12 month old sleeps around 12.5–14 hours per 24 hours: roughly 10–11 hours at night and about 2–3 hours during the day split across 2 naps. These are broad averages, not a target to hit exactly — plenty of healthy toddlers sleep a little more or less. What matters isn’t the precise number, but that your child wakes up reasonably rested and isn’t accumulating overtiredness day after day.
Wake windows at 12 months
The wake window is how long your toddler can comfortably stay awake between sleeps. At 12 months it’s usually 3.5 to 4.5 hours, and the pattern across the day looks like this:
- The first window of the morning is the shortest.
- The window before bedtime is the longest, often stretching toward 4.5 hours or a touch beyond as the eventual move to one nap gets closer.
Age gives you a starting point, but sleepy cues are the real guide: rubbing eyes, going quiet, losing interest in play, or getting suddenly clingy or fussy. At this age toddlers are often so busy practicing new skills — standing, cruising, maybe walking — that they’ll push straight through tired signals if you wait too long to start winding down.
| Age | Wake window | Naps/day | Total sleep ~24h |
|---|---|---|---|
| 10 months | 3–4 h | 2 | ~13–14 h |
| 11 months | 3.5–4.5 h | 2 | ~13–14 h |
| 12 months | 3.5–4.5 h | 2 | ~12.5–14 h |
How many naps does a 12 month old take
Most 12 month olds are still on 2 naps — a morning nap and an early-afternoon nap. It can feel like the first birthday should come with a nap change, but for the large majority of toddlers it doesn’t, at least not yet.
The 2-nap pattern still works best when:
- The morning nap is capped so it doesn’t eat into the afternoon nap.
- The afternoon nap wraps up by roughly 3:00–3:30 pm, so bedtime doesn’t get pushed too late.
- Short-nap days get an earlier bedtime to absorb the extra tiredness.
Twelve months is also a very common age for parents to start wondering if a nap drop is near, especially if the morning nap gets fought once or twice. In almost all cases it isn’t yet — the 2-to-1 nap transition typically doesn’t land until 15–18 months. A day or two of nap resistance is usually a growth spurt, a developmental leap, or a schedule slightly out of sync — not a signal to drop anything. Real readiness looks like consistent morning-nap refusal for a week or two straight while the afternoon nap still goes fine. Until then, holding the 2-nap rhythm is what prevents an overtired, harder-to-settle toddler.
12 month old sleep schedule: hour-by-hour sample (2 naps)
Here’s a realistic 2-nap sample for a toddler who wakes around 7:00. Adjust it to whenever yours wakes up — the windows matter more than the exact clock.
| Time | What’s happening | Prior window |
|---|---|---|
| 7:00 | Wake + feed | — |
| 9:45 | Nap 1 (~1–1.25 h) | ~2.75 h |
| 14:00 | Nap 2 (~1–1.5 h) | ~3.25 h |
| 19:15 | Routine + bedtime | ~4 h |
And a short-nap-day version, for when naps come out brief and you need to protect the night:
| Time | What’s happening | Prior window |
|---|---|---|
| 7:00 | Wake + feed | — |
| 9:45 | Nap 1 (~35–40 min) | ~2.75 h |
| 13:30 | Nap 2 (~35–40 min) | ~3 h |
| 18:15 | Routine + earlier bedtime | ~3.25 h |
Notes to make it actually work:
- On short-nap days, move bedtime earlier (even 6:15–6:30 pm) — this is the single best defense against overtiredness.
- If a nap comes out very short, trim the next window a little to make up for the extra tiredness.
- At 12 months, three meals a day of mostly family food is typical, and many toddlers transition from formula to whole cow’s milk around now (breastfeeding can continue as long as you both like). Milk is no longer the main source of calories — food takes the lead. Your pediatrician can help you judge timing and amounts for your child.
Is a nap transition actually near? What to check
A few signs suggest the 2-to-1 nap switch is genuinely getting close — usually not before 15 months, and often later:
- Consistent morning-nap refusal for 7–10 days straight, not an isolated bad day.
- The afternoon nap stays strong and unaffected.
- Bedtime doesn’t get noticeably harder even without the extra rest.
- Your toddler seems bright and content on a shorter total sleep, rather than wired-and-overtired.
If you’re only seeing one rough day here and there, the far more common culprits are a growth spurt, teething, a developmental leap (standing, cruising, first steps), or a wake window that’s crept slightly out of sync — not a true nap transition. Riding it out with a steady routine almost always settles things back down.
What helps the schedule click into place
1. Wake windows by age, not a rigid clock
Overtiredness is the number-one amplifier of sleep problems: too much awake time floods the body with cortisol and makes settling harder — and at 12 months, with new mobility to practice, an overtired toddler often fights sleep even more. Lean on wake windows by age and your toddler’s cues rather than a fixed time.
2. A short, predictable bedtime routine
A brief, repeatable wind-down remains one of the best sleep tools there is. The NHS recommends a consistent routine — for example a bath, pajamas, a feed or snack, and a quiet book or song — to signal that sleep is coming. Keep the last 20–30 minutes screen-free. As independence and opinions grow, the predictability of the routine itself is often what your toddler finds most reassuring.
3. Chances to fall asleep drowsy-but-awake
If your toddler only falls asleep nursing or being held, they may need that same help resettling between sleep cycles overnight. Giving them a chance to settle at the start of the night, put down drowsy but awake, helps them link cycles on their own. It’s gradual and gentle — it is not leaving them to cry.
4. A sleep environment that supports rest
A dark room, steady white noise, and a comfortable temperature (often 68–72°F / 20–22°C) make it easier to fall asleep and resettle, especially while your toddler is testing out standing, cruising, or new steps at odd hours. A sleep sack (wearable blanket) is safer than loose blankets at this age.
5. Safe sleep, always first
At 12 months your toddler is moving constantly, so safe sleep still comes first. The American Academy of Pediatrics (AAP) recommends placing your baby on their back for every sleep, on a firm, flat surface, with no loose bedding, pillows, soft toys, or bumpers, and room-sharing without bed-sharing when possible. Once your toddler moves confidently on their own, it’s fine if they change position during sleep — but you always put them down on their back. Make sure the crib mattress is set to its lowest position now that your toddler can pull up and stand.
When the schedule “doesn’t fit” (and what to check)
If you’ve been trying a schedule for days and sleep is still off, it’s usually one of these causes, not because the sample is wrong:
- Windows too long → overtiredness → short naps, night wakings, and early morning rising.
- Windows too short → not enough “sleep pressure” and your toddler resists or takes ages to fall asleep.
- A morning nap that runs too long → it borrows from the afternoon nap and the day unravels.
- A developmental leap (standing, cruising, first steps, new words) that temporarily disrupts sleep.
- A too-early nap drop — dropping to 1 nap before 15 months almost always backfires into overtiredness.

When to check with your pediatrician
Sleep ups and downs at this age are usually normal. But check in with your pediatrician if you notice persistent snoring or breathing pauses during sleep, poor weight gain or feeding difficulties, extreme daytime sleepiness, or anything that simply worries you. A sleep schedule is a support tool — it never replaces a clinical check.

The bottom line
At 12 months, a good schedule still rests on the same three pillars as the months before: wake windows of 3.5–4.5 hours, 2 solid naps, and a steady bedtime routine, all on a foundation of safe sleep. A rough day or two doesn’t mean the nap transition has arrived — that’s still usually months away. Start with the sample above, protect an early bedtime on short-nap days, and hold the rhythm steady while your toddler practices all the exciting new skills this birthday year brings.
