12 Month Old Sleep Schedule: Naps, Bedtime & Wake Windows
Optimal sleep schedule for your 12 month old. Total sleep hours, nap timing, wake windows, and bedtime routine. Includes sample schedules.
📚 How Much Sleep Does a 12-Month-Old Need?
Your 12-month-old needs approximately 12 to 14 hours of total sleep per day. At this age, most babies are still solidly on a 2-nap schedule, sleeping 10 to 12 hours at night and napping for a combined 2 to 3 hours during the day. The first birthday is a common time for sleep disruptions, so understanding what's normal helps you avoid making changes that backfire.
- Total sleep in 24 hours: 12–14 hours
- Nighttime sleep: 10–12 hours (the vast majority of 12-month-olds can sleep without feeds)
- Daytime sleep: 2–3 hours across 2 naps
- Morning nap: typically 1–1.5 hours
- Afternoon nap: typically 1–1.5 hours
🔑 Wake Windows at 12 Months
At 12 months, wake windows have grown to 3.5 to 4 hours. This is a noticeable jump from just a few months ago, and it's the reason the schedule feels like it's getting "tighter" — fitting 2 naps into the day with these longer wake windows requires careful timing. If bedtime is creeping past 8:00 PM, it may be a signal that the nap transition is approaching in the coming weeks or months.
- Wake window 1 (wake to nap 1): 3.5 hours
- Wake window 2 (nap 1 to nap 2): 3.5–3.75 hours
- Wake window 3 (nap 2 to bedtime): 3.75–4 hours
- Total awake time across the day: roughly 10–11 hours
- If the second nap is pushing past 3:30 PM, consider capping nap 1 at 1 hour to protect the schedule
✨ Sample 12-Month-Old Daily Schedule
Here's a typical 2-nap schedule for a 12-month-old. By this age, your baby is eating 3 meals of solid food plus milk (breast or formula, transitioning to whole milk after 12 months), so the schedule includes both feeding and sleep timing.
- 7:00 AM — Wake up, milk, breakfast (whole grain toast with nut butter, banana, yogurt)
- 10:30 AM — Nap 1 begins (cap at 1.25 hours if nap 2 has been difficult)
- 11:45 AM — Wake from nap 1
- 12:00 PM — Lunch (soft chicken pieces, steamed broccoli, pasta, fruit)
- 2:00 PM — Milk feed or snack
- 3:15–3:30 PM — Nap 2 begins (1–1.25 hours)
- 4:30 PM — Wake from nap 2, snack, active play
- 5:30 PM — Dinner
- 7:00 PM — Begin bedtime routine: bath, pajamas, book, milk, song
- 7:30–8:00 PM — In crib, asleep for the night
🌙 The 12-Month Sleep Regression
The 12-month sleep regression is one of the most disruptive because it happens alongside a surge in physical and cognitive development. Your baby may be taking first steps, saying first words, and discovering their own willpower — all of which make sleep feel less appealing. Here's what to expect and how to handle it.
- Common signs: fighting bedtime, refusing the second nap, increased night waking, early morning waking
- Root causes: walking or pre-walking motor development, language explosion, growing independence and testing boundaries
- Duration: typically 2–4 weeks, though some babies experience disruptions for up to 6 weeks
- Do NOT drop to 1 nap in response — this almost always makes things worse at this age
- Stay consistent with your existing sleep approach and bedtime routine
- If nap 2 is being refused, offer quiet crib time for the full nap period — many babies will eventually fall asleep after 15–20 minutes
- An earlier bedtime (6:30–7:00 PM) on skipped-nap days prevents a snowball of overtiredness
🔄 Signs the 2-to-1 Nap Transition Is Approaching
While most 12-month-olds aren't ready to drop to 1 nap yet, it's helpful to know what genuine readiness looks like so you can distinguish it from the regression. The transition typically happens between 13 and 18 months.
- Your baby consistently takes 20+ minutes to fall asleep for nap 2, for at least 2–3 consecutive weeks (not just a few days)
- Nap 2 is pushing so late that bedtime is consistently after 8:00 PM
- Your baby can handle 4.5+ hours of wake time without becoming a mess
- Morning nap is still happening easily — it's specifically the second nap that's the problem
- Night sleep is being disrupted (split nights, long wakings) because of too much daytime sleep
- If fewer than 3 of these signs are present, stick with 2 naps and adjust timing instead
🔮 Sleep Sacks, Loveys, and What's Changing
At 12 months, a few things shift. The AAP considers it safe to introduce a small comfort object (lovey) into the crib. Your baby may be ready for whole milk instead of formula. And you may be wondering about the sleep sack. Here's a quick guide to these transitions.
- Sleep sacks: keep using them. They help prevent climbing, provide warmth without loose blankets, and serve as a sleep cue. Most toddlers use them until age 2–3
- Loveys: a small, breathable comfort object (no bigger than a washcloth-sized stuffed animal) is now safe per the AAP. Introduce it during the bedtime routine so your baby associates it with comfort
- Milk transition: work with your pediatrician on transitioning from formula to whole milk. This is a nutrition change, not a sleep change — but sometimes the switch temporarily affects sleep
- Blankets and pillows: NOT yet recommended. Keep the crib bare except for a fitted sheet, sleep sack, and optionally one small lovey
- Crib mattress should already be on the lowest setting. If your baby is attempting to climb, a sleep sack is your best prevention tool
