12 Month Sleep Schedule: Naps, Wake Windows, Sample Day

Your baby just turned one, and the question on every parent’s mind is simple: how much sleep does a 12 month old actually need, and when? The good news is that the first birthday is usually a stable patch, not a big transition. Most 1 year olds keep the two-nap rhythm they have had for months.

Below is a practical 12 month sleep schedule with realistic numbers. Treat it as a starting frame, not a rigid rulebook. Every toddler is different, and your child’s mood and night sleep tell you more than any chart.

How much sleep does a 12 month old need?

Across 24 hours, most 1 year olds need roughly 12-15 hours of total sleep, with about 10-12 hours at night and 2-3 hours split across two daytime naps. Some babies sit at the lower end and some at the higher end, and both can be perfectly normal.

• Total sleep in 24 hours: about 12-15 hours
• Night sleep: about 10-12 hours
• Daytime naps: 2 naps, totaling roughly 2-3 hours
• Wake windows: about 3-3.5 hours between sleeps

Wake windows at 12 months

A wake window is the stretch of awake time between sleeps. At 12 months it usually lands around 3 to 3.5 hours, often a touch shorter before the first nap and a touch longer before bedtime. Watching the clock and your baby’s tired cues together works better than either one alone.

• Morning to first nap: around 3 hours
• Between the two naps: around 3-3.5 hours
• After the second nap to bedtime: around 3.5-4 hours
• Tired cues: rubbing eyes, looking away, getting clumsy or clingy

A sample 12 month two-nap day

Here is a calm, typical day for a 1 year old waking around 7 in the morning. Shift every time to match your own wake-up; the gaps matter more than the exact clock.

• 7:00 - wake and morning milk plus breakfast
• 10:00 - first nap, about 1 hour
• 11:00 - wake, lunch, play
• 2:30 - second nap, about 1-1.5 hours
• 4:00 - wake, snack, outdoor time
• 7:30 - bedtime routine and lights out

Is your 1 year old ready for one nap?

Many parents worry about the 2-to-1 nap transition at exactly 12 months, but most babies are not ready yet. The shift to a single midday nap more often happens between 14 and 18 months. Hold the second nap as long as it is working.

This article is educational guidance and not medical advice. If your child’s sleep, breathing, or growth worries you, please speak with your pediatrician.

• Naps suddenly fight bedtime or push it very late
• The second nap is consistently refused for 2 weeks or more
• Early-morning wakeups appear with two short naps
• When in doubt, drop to one nap slowly and keep an eye on night sleep

FAQ

How many naps should a 12 month old take?

Most 1 year olds still take 2 naps a day, usually a mid-morning nap and an early-afternoon nap. Dropping to one nap typically comes later, often around 14-18 months, so do not rush it at the first birthday.

What are good wake windows for a 12 month old?

Plan for about 3-3.5 hours awake between sleeps. The first window of the day is often the shortest, and the last window before bedtime is usually the longest, closer to 3.5-4 hours.

What time should a 1 year old go to bed?

A bedtime between roughly 7 and 8 in the evening suits most 1 year olds, landing about 3.5-4 hours after the second nap ends. Watch the gap from the last nap rather than fixing on one exact time.

Why is my 12 month old waking at night again?

Brief regressions are common at this age due to teething, new motor skills like walking, separation awareness, and naps that run too long or too short. Keep the routine steady, and if waking persists for weeks, check in with your pediatrician.
