10, 11 & 12 Month Old Sleep Schedule: Naps, Wake Windows & Sample Day
From 10 to 12 months, wake windows stretch to 3-4 hours and most babies are on a solid 2-nap routine with long, consolidated nights. The big temptation at this age is dropping to one nap too early -- most babies aren't ready until 15-18 months.
This is the final stop in the baby sleep schedule by age series. Coming from the 7-9 month schedule? Expect noticeably longer awake stretches.

Don't drop to one nap yet
Around 10-12 months, many babies briefly fight a nap, which tempts parents into a premature 1-nap switch. Usually it's a phase, a regression, or too much wake time -- not a true nap drop. Most babies need 2 naps until 15-18 months. Hold the second nap; if naps resist, nudge wake windows slightly longer rather than cutting a nap.
The 12-month regression
Near the first birthday, a developmental leap (cruising, walking, words) can disrupt sleep and make one nap look tempting. Keep both naps and a consistent bedtime routine and it usually settles.
Night sleep at 10-12 months
Most babies sleep 11-12 hours overnight, ideally without feeds. If early-morning waking creeps in, check that day sleep isn't excessive and that bedtime isn't too early or too late. A dark, cool room and white noise help.
Safe sleep at 10-12 months
Back to start, sleep sack, empty crib on the lowest mattress setting. As your baby pulls up and stands, remove anything they could climb on. Review safe sleep basics.
This is exactly what Baby Signal is built for. Instead of guessing whether a short nap means the wake window was too long or too short, you describe what happened -- "down at 9:15, took 25 minutes to settle, woke after 35" -- and get one clear adjustment shaped by your baby's age and history. Get Baby Signal and stop second-guessing the clock.
The takeaway
A 10-12 month old sleep schedule runs on 2 naps and 3-4 hour wake windows with long, consolidated nights. Resist dropping to one nap before 15-18 months -- most early nap battles are a phase, not a true transition. Revisit the full schedule-by-age guide any time your baby's needs shift.
Frequently asked questions
How long should a 10-12 month old be awake between naps?
About 3 to 4 hours. Use roughly 3 hours before the first nap and 3.5-4 hours before bedtime, adjusting to tired cues.
Should a 12 month old be on 1 or 2 naps?
Two naps. Most babies aren't ready for one nap until 15-18 months. Early nap battles at 10-12 months are usually a phase or regression, not a true nap drop.
How much should a 1 year old sleep?
About 12-14 hours total -- roughly 11-12 hours overnight plus 2-3 hours of day sleep across 2 naps.
Why is my 11 month old waking early?
Common causes are too much daytime sleep, a bedtime that's too early or too late, or light and noise in the morning. Adjust day sleep, keep the room dark, and use white noise.
