8-Month-Old Sleep Schedule

Eight months old, and your baby has places to be. Crawling across the room, pulling up on furniture, grabbing the dog's tail. The energy is relentless during the day. And at night? Suddenly they're clinging to you like you might vanish forever.

This is a weird stretch. The days are fun. The nights can be rough.

How much sleep does an 8-month-old need?

Most 8-month-olds need about 14 hours of total sleep per day. The AASM recommends 12 to 16 hours for infants 4 to 12 months, naps included.¹ The National Sleep Foundation's range is 12 to 15.²

In practice, that typically breaks down to about 10.5 hours at night and 3 to 3.5 hours during the day.³ A 2012 systematic review of 34 studies found normal infant sleep ranged from 9.7 to 15.9 hours, so there's plenty of room for individual variation.⁴

If your baby consistently gets 13 hours and wakes up happy, that's their number. Don't chase a chart.

Our sleep needs by age guide has the full breakdown.

Wake windows at 8 months

At 8 months, wake windows run about 2 hours 20 minutes to 3 hours 15 minutes, with a typical window around 2 hours 45 minutes (165 minutes).

The first window of the day is still the shortest. Most 8-month-olds are ready for nap one about 2 to 2.5 hours after waking. Pediatric sleep consultants consistently put this first window at about 80% of the midday window.⁵ The last window before bed is slightly shorter than midday too (roughly 85% of the midday window), because pushing bedtime too late leads to overtiredness, which makes falling asleep harder, not easier.

These windows are noticeably longer than just a couple months ago. Your baby's ability to stay awake and engaged is growing fast.

Our wake windows chart covers all ages.

How many naps at 8 months?

This is the transitional zone. At 8 months, most babies are moving from 3 naps to 2, and many have completed the switch already. The typical range for this transition is 6 to 9 months, with most babies landing on 2 naps between 7 and 8 months.⁶

What does 2.5 naps look like in real life? Some days your baby takes two solid naps and is fine until bedtime. Other days they're falling apart by 4 PM and need a quick catnap to bridge the gap. That inconsistency is normal during the transition. It usually sorts itself out within a few weeks.

Individual naps at this age run 60 to 90 minutes.³ If your baby is still on 3 naps and doing well, there's no rush. But if that third nap is shrinking to 15 minutes or they're fighting it entirely, it's time.

Our nap transition guide covers the 3-to-2 switch in detail.

A sample day

This is a 2-nap schedule, which is where most 8-month-olds land. If your baby still needs an occasional third catnap, tack on a short one around 4 PM and adjust bedtime slightly later.

Time	Activity
6:30 AM	Wake up, milk feed (breast or bottle)
7:15 AM	Play, floor time, crawling practice
9:00 AM	Nap 1 (1 to 1.5 hours)
10:15 AM	Wake, milk feed
10:45 AM	Solids (breakfast), play
12:00 PM	Play, outdoor time
1:00 PM	Nap 2 (1 to 1.5 hours)
2:30 PM	Wake, milk feed
3:00 PM	Solids (lunch), play, exploration
5:00 PM	Solids (dinner), milk feed
6:00 PM	Bedtime routine (bath, pajamas, book, feed)
6:45 PM	Bedtime

An early bedtime feels wrong, but research supports 6:30 to 7:30 PM for this age.⁵⁷ Earlier bedtimes are associated with longer, more consolidated nighttime sleep. Scientists think this aligns with the infant circadian rhythm, which drives a strong melatonin surge in the early evening.⁸

Notice the wake windows aren't identical. First window is about 2.5 hours, midday stretches to nearly 3, and the last one before bed compresses to about 2.25 hours. That pattern is intentional.⁵

Bad nap days will happen. If nap 2 was only 30 minutes, pull bedtime earlier. If both naps were short, you might need an emergency catnap and a slightly later bedtime. Flexibility is the whole point.

The 8-month sleep regression

If your baby was sleeping well and suddenly isn't, you're probably dealing with the 8 to 10 month regression. It typically hits between 7.5 and 10 months, and separation anxiety is the primary driver.

Your baby has figured out object permanence. They now understand that when you walk out of the room, you still exist somewhere else. The problem? They want you back. Immediately. Especially at 2 AM.⁹

Motor development compounds it. Crawling, pulling to stand, cruising. Research by Scher and Cohen found that crawling onset is directly linked to increased night wakings, and that infants who crawled earlier showed more sleep disruption.¹⁰ A related study found the same pattern with pulling to stand.¹¹ Your baby's brain is rehearsing these new skills even while asleep.

In practice, you'll see more night wakings (with actual crying, not just fussing), longer fights at bedtime, crib protests when you leave the room, and general clinginess during the day. Naps might get shorter or harder to start.

The most useful thing you can do is practice separations when everyone's calm. Peekaboo, leaving the room for 30 seconds and coming back cheerfully. These games reinforce that you always return. And keep the bedtime routine consistent. A predictable sequence (bath, pajamas, book, song, bed) gives your baby a sense of security even when everything else feels wobbly.⁷

This regression usually lasts 2 to 6 weeks. It passes. Our sleep regression guide goes deeper.

Feeding and sleep at 8 months

By 8 months, most babies are on 3 to 5 milk feeds (breast or bottle, 180 to 240 ml per feed) plus 3 solid meals per day.¹² This is the age when finger foods start appearing. Soft chunks of banana, steamed sweet potato, small pieces of toast. Your baby is practicing the pincer grasp and wants to feed themselves (messily).

For night feeds: most 8-month-olds don't need to eat overnight from a nutritional standpoint.¹³ Some still have one feed, and that's fine. If your baby wakes multiple times to eat, it might be habit rather than hunger, especially if they're eating well during the day.

Timing solids around naps takes some juggling. Offer solids about 30 to 60 minutes after a milk feed, during a wake window. Heavy meals right before sleep can cause discomfort. And new textures or allergen introductions are better earlier in the day, when you can watch for reactions.

Our feeding guide has age-by-age amounts and schedules.

Common problems at this age

The one you'll hear about from every parent of an 8-month-old: standing up in the crib and not knowing how to get back down. Your baby pulls to stand, gets stuck, and cries. During the day, practice sitting back down from standing. Hold their hands and guide them. Within a week or two the nighttime drama fades.

Separation anxiety at bedtime is the other big one. If your baby screams when you leave the room, try a more gradual approach. Sit near the crib for a few nights, then move your chair a bit farther away each night. Verbal reassurance from the hallway can help too.

Early morning wakes (before 6 AM) are usually caused by bedtime being too late, the room getting light, or too much daytime sleep. Blackout curtains help more than you'd think. If the last nap runs past 4 PM consistently, cap it or drop it.

Nap lengths will bounce around. One day they sleep 90 minutes, the next day 30. During the 3-to-2 transition, this is expected. It stabilizes once your baby is firmly on 2 naps with appropriate wake windows.

Frequently Asked Questions

How do I know if my 8-month-old is ready for 2 naps?

If the third nap consistently shrinks below 20 minutes, your baby fights it for 15+ minutes, or it pushes bedtime past 7:30 PM, it's time to drop it. You might need to move bedtime a little earlier for a week or two while your baby adjusts to the longer wake windows.

Should I sleep train during the 8-month regression?

Starting a brand-new sleep training method during a regression isn't ideal. Your baby's system is already stressed from developmental changes. If you've been working on independent sleep and things regressed, stay consistent with what you were doing. If you haven't started yet, wait until the regression passes (usually 2 to 6 weeks) and things stabilize.

Can an 8-month-old sleep through the night?

Many can and do. By 8 months, babies are physically capable of going 10 to 11 hours overnight without a feed.⁷¹³ Whether yours does depends on how they fall asleep, whether they can connect sleep cycles independently, and how they handle the separation anxiety that peaks at this age.

Why does my 8-month-old suddenly hate the crib?

Probably separation anxiety. At 8 months, your baby understands that you're leaving and they don't like it. This is actually a sign of healthy attachment and cognitive development. It doesn't mean something is wrong. Extra comfort during the bedtime routine, a consistent sequence, and brief check-ins can help them adjust.
