12 Month Old Sleep Schedule
Twelve months is a transition age. Wake windows stretch to 3–4 hours, total sleep is 12–14 hours, and most toddlers are either dropping to one nap or right at the edge of it. The 12-month sleep regression — driven by walking, language, and the nap transition — can briefly disrupt a settled sleeper. Hold your routine steady; the schedule you build now carries you through the toddler years.

At this age your baby can comfortably stay awake for 3h–4h between sleeps (the "12–15 months" band). Most 12 month babies take 2 naps a day and sleep 12–14 hours (day nap + night sleep). Use the wake window — not the clock — as your main signal for when the next sleep is due.

Illustrative rhythm — every baby varies. Use wake windows rather than the clock to time sleep.
| Time | What happens |
|---|---|
| 7:00 AM | Wake, breakfast + cup of milk |
| 9:30–10:30 AM | Nap 1 (morning — often short or dropping) |
| 10:30 AM | Wake, snack |
| 1:30–3:00 PM | Nap 2 (becoming the single midday nap) |
| 3:00 PM | Wake, snack + milk |
| 7:00 PM | Bedtime routine, sleep |
| Night | ~11h |
Bedtime routine
A predictable bedtime routine cues your baby that sleep is coming and makes settling easier. At this age, aim for a calm 20–30 minute wind-down in the same order every night. A simple sequence:
- Bath or wash — warm water lowers body temperature, a natural sleep signal.
- Feed — milk in a dim, quiet room; burp well before lying down.
- Book or song — two short books or one familiar lullaby.
- Swaddle or sleeping bag — a clear "sleep time" cue.
- Into the crib drowsy but awake — the single most important sleep-shaping habit at every age.
Lay your baby down calm but not fully asleep so they learn to connect sleep cycles themselves. If they fuss, pause briefly before soothing — many settle within a minute. See our fuller bedtime routine guide for age-by-age variations.
Common sleep challenges at this age
- The 2-to-1 nap transition. Usually complete between 13 and 18 months, but starts earlier for some. Signs: refusing the second nap, the morning nap creeping later, or a long first nap and a skipped second. Move gradually to one midday nap (12:30–2:30) with an earlier bedtime during the transition.
- 12-month sleep regression. Walking, a language burst, and the nap transition combine to disrupt sleep for 2–6 weeks. Resist the urge to reintroduce sleep associations; hold the routine and your toddler will resettle.
- Nap refusal. A refused nap often means your toddler is ready for a longer wake window or the transition to one nap. If they refuse the second nap for several days, try one midday nap and a slightly earlier bedtime.
Frequently asked questions
What is the wake window for a 12-month-old?
About 3 to 4 hours (180–240 minutes). If still on two naps, the wake windows are typically 3h / 3.25h / 3.5h. On one nap, a single 4.5–5 hour wake window before and after the nap is normal.
How many naps at 12 months?
Most are on 1–2 naps. Some toddlers settle onto a single midday nap as early as 12 months; others need two naps until 15–18 months. Follow your child's signs rather than the calendar.
Is the 12-month sleep regression real?
Yes — it is driven by walking, language development, and the nap transition, and can last 2–6 weeks. Holding routines steady and offering reassurance without reintroducing old sleep associations is the fastest way through it.
