9, 10, 11 and 12 month old sleep schedule: two naps, wake windows and routines

A sleep routine for a 9, 10, 11, or 12 month old is the most stable two-nap rhythm of the entire first year—provided you know how to cap daytime naps as your baby’s stamina grows. Once the 3-to-2 nap shift is behind you (covered in our 6 to 8 month sleep schedule), your baby settles into a predictable clock-based day anchored by two naps and three solid meals.

The main trap between 9 and 12 months is mistaking a sudden afternoon nap strike at 10 or 11 months for readiness to drop to one nap. Below is how wake windows and nap caps shift from 9 through 12 months, a complete worked daily schedule for a 10-month-old, and how to stop Nap 1 from cannibalizing Nap 2.

How do 9-month vs. 10-month vs. 11–12 month sleep schedules compare?

Comparing a 9-month schedule versus a 10-month routine versus an 11-to-12-month schedule shows that the two-nap structure stays intact while total awake time increases from 9.75 hours at 9 months to 10.75–11 hours by 12 months, and daytime nap sleep trims from 2.75 hours down to 2–2.25 hours.

Metric	9 Months	10 Months	11–12 Months
Wake windows (morning / midday / bed)	3 hr / 3.25 hr / 3.5 hr	3 hr / 3.5 hr / 3.75–4 hr	3.25 hr / 3.5–3.75 hr / 4 hr
Number of naps	2 naps	2 naps	2 naps (do not drop to 1 nap yet)
Nap 1 & Nap 2 targets	75–90m + 75–90m (2.5–3 hr total)	60–75m + 75–90m (2.25–2.5 hr total)	Cap Nap 1 at 60m + 60–75m Nap 2 (2–2.25 hr total)
Target night sleep	11–11.5 hours	10.5–11.5 hours	10.5–11 hours
Total 24-hour sleep (AASM)	12–15 hours	12–14.5 hours	12–14 hours

What does a worked daily sleep and feeding routine for a 10-month-old look like?

Because sleep routine for 10 month old is the single most searched schedule query in this age bracket, here is the exact hour-by-hour day starting at 7:00 am, integrating milk feeds, three solid meals, and two naps:

• 07:00 am – Wake-up & Milk Feed #1: Open the curtains immediately for morning daylight and offer breastmilk or a 6–8 oz bottle.
• 08:00 am – Breakfast Solids: Iron-rich oatmeal, egg strips, or yogurt with fruit, followed by active floor crawling and standing practice.
• 10:00 am to 11:15 am – Nap 1 (75 minutes): Placed into the cot awake after a 3-hour morning window. Wake gently by 11:15 am so enough sleep pressure remains for the afternoon.
• 11:30 am – Milk Feed #2: Breastfeed or bottle after waking.
• 12:30 pm – Lunch Solids: Protein, vegetables, and healthy fats, followed by outdoor stroller or park time.
• 02:30 pm to 03:45 pm – Nap 2 (75 minutes): Placed down after a 3.25-hour midday window. Wake by 3:45 pm–4:00 pm at the latest to protect bedtime.
• 04:00 pm – Milk Feed #3 (or Afternoon Snack at 11–12 months): Breastfeed or bottle upon waking.
• 05:30 pm – Family Dinner Solids: Finger foods at the table, followed by active floor play and climbing practice.
• 06:45 pm – Bedtime Routine & Final Milk Feed #4: Warm bath, milk feed in a lit or dim room (finished 20 minutes before cot placement), tooth brushing, sleep sack, two books, and into the cot wide awake at 07:30 pm.

Why do 10 to 12 month olds suddenly fight Nap 2 (and why you should keep 2 naps)?

Between 10 and 12 months, thousands of parents assume their baby is ready for a 1-nap toddler schedule because the child stands in the cot babbling and refusing Nap 2 for a week. In reality, fewer than 8% of babies can handle a 5-hour morning wake window at 10 or 11 months without crashing into chronic overtiredness.

What is actually happening is a sleep-budget squeeze: your baby’s total 24-hour sleep need has dropped by 30 minutes, so a generous 90-to-120-minute morning nap uses up too much of their daytime sleep budget, leaving zero adenosine for 2:30 pm.

Follow this 5-step Nap-1-Cap protocol to save the two-nap schedule through 14 to 15 months (when the real transition happens, covered in our when to drop to one nap guide):

1. Anchor Nap 1 no earlier than 9:45 am–10:00 am (assuming a 6:45 am–7:00 am wake-up), even if your baby woke early at 5:45 am.
2. Cap Nap 1 strictly at 60 minutes. Wake your baby at the 60-minute mark so they have a full 3.5-hour midday window to build sleep drive before Nap 2.
3. Offer Nap 2 at 2:30 pm–2:45 pm. With Nap 1 capped at an hour, most 10-to-12-month-olds go straight back to sleeping 60 to 90 minutes in the afternoon.
4. Wake from Nap 2 by 4:00 pm. This preserves a full 3.75-to-4-hour final wake window before a 7:45 pm–8:00 pm bedtime.
5. Hold the adjusted times for 5 full days. Only if your child is over 13 to 14 months and still refuses Nap 2 for 10+ days despite a 45-to-60-minute capped Nap 1 is it time to move to one nap.

How do you balance solid meals and milk feeds at 9 to 12 months?

Between 9 and 12 months, solid meals gradually move from a sensory side-dish to the main daytime calorie anchor, while breastmilk or formula remains the primary source of liquid nutrition (typically 3 to 4 breastfeeds or 16 to 24 oz of formula across 24 hours).

At 9 and 10 months, offer milk upon waking from night sleep and each nap, followed by breakfast, lunch, and dinner solids 45 to 60 minutes later so your baby arrives at the highchair hungry. By 11 and 12 months, flip the midday and evening order—offering lunch and dinner solids first and milk 30 minutes afterward—to prepare smoothly for toddlerhood.

How do you handle standing in the cot, separation anxiety, and 5:00 am wakes?

At 9 to 12 months, babies realize that when you walk out the nursery door, you continue existing in the hallway without them. Separation anxiety and newly acquired standing skills frequently turn bedtime or 5:00 am light sleep into a standing protest at the cot rail.

Give your baby plenty of daytime control: practice walking or cruising during every wake window, never sneak out of a room during the day without a cheerful wave and “I’ll be right back,” and if they stand in the cot at bedtime, pat the mattress and say “Time to lie down” once rather than physically laying them down 30 times in a row (which quickly turns into a thrilling game of jack-in-the-box).

Why does a 9 to 12 month old wake up at 5:00 am (and how do you shift it)?

Early 5:00 am wake-ups between 9 and 12 months are almost always driven by an overly early first nap (before 9:30 am) or more than 2.75 hours of total daytime sleep. When a baby wakes at 5:15 am and goes back down for Nap 1 at 8:00 am, the brain treats Nap 1 as the final sleep cycle of the night—locking in the 5:15 am wake-up permanently.

To move morning wake-up back past 6:30 am, keep the bedroom completely dark until 6:15 am, push Nap 1 toward 9:30 am–9:45 am by adding 15 minutes every two days, and cap total daytime sleep across both naps at 2.25 to 2.5 hours.

When should you talk to a paediatrician about 9 to 12 month sleep?

While developmental regressions around standing, cruising, and separation anxiety are normal between 9 and 12 months, persistent sleep fragmentation alongside physical symptoms warrants a medical check. Low iron stores (especially in breastfed babies after 6 months), habitual mouth breathing, snoring, ear fluid, or eczema flare-ups frequently masquerade as behavioural sleep problems.

If you decide to use structured check-ins once physical causes are ruled out, review our sleep training methods compared guide and verify your windows on the wake windows by age chart.
