Quick Answer
Wake windows for an 8 month old are typically 2.5 to 3.5 hours. Most 8 month olds are on 2 naps. This is also the beginning of the 8 to 10 month regression — one of the most disruptive developmental periods of the first year — which makes wake window accuracy especially important.
What are wake windows at 8 months?
At 8 months, wake windows have extended significantly from earlier in the first year. The appropriate range is 2.5 to 3.5 hours, with the window before bedtime often being the longest.
Eight months is also the beginning of the 8 to 10 month developmental regression — driven by crawling, pulling to stand, and object permanence. During the regression, holding the schedule as consistently as possible is the most effective approach.
Wake window ranges at 8 months
First wake window: 2.5 to 3 hours
Between naps: 2.5 to 3 hours
Final window before bed: 3 to 3.5 hours
Sample schedule for an 8 month old
7:00am — Wake and feed. 9:30–10:00am — Nap 1 (1 to 1.5 hours). 11:00–11:30am — Wake from nap 1. 2:00–2:30pm — Nap 2 (1 to 1.5 hours). 3:30pm — Wake from nap 2. 7:00–7:30pm — Bedtime.
The 8-10 month regression and wake windows
The 8 to 10 month regression typically begins around 8 months. During this period, nap refusal, night waking, and bedtime resistance are all common. The most important thing is to hold wake windows within the appropriate range even when the regression is making everything harder. See our full 8-10 month sleep regression article for detailed guidance.
Standing in the cot and wake windows
At 8 months, many babies learn to pull to stand. This affects sleep in two ways: babies wake themselves practising the skill, and once standing they cannot get back down. The most effective fix is practising lowering from standing during the day.
Frequently Asked Questions
What are the wake windows for an 8 month old?
Typically 2.5 to 3.5 hours. The first wake window is usually around 2.5 to 3 hours, with the final window before bedtime extending to 3 to 3.5 hours.
How many naps does an 8 month old need?
Most 8 month olds are on 2 naps. Total daytime sleep of 2.5 to 3.5 hours is typical.
My 8 month old is refusing the second nap — should I drop it?
Almost certainly not. Nap refusal during the 8 month regression is driven by developmental disruption, not schedule readiness. Most babies are not ready to drop to one nap until 13 to 18 months.
How long does the 8-month sleep regression last?
The developmental component typically resolves within 3 to 6 weeks.
