Quick answer: The 8 month sleep regression usually lasts 2 to 6 weeks. It's driven by big new skills like crawling, pulling to stand and separation anxiety, plus the move from 3 naps to 2. Unlike the 4 month regression, it passes, as long as new habits don't take root while it's happening.
It is 2:13 a.m. and your baby is standing in the crib, holding the rail, crying because they have no idea how to get back down. Two weeks ago this same baby slept 11 hours. It is real, it is common, and it does end.
What causes the 8 month sleep regression?
This is not your baby forgetting how to sleep. It's a busy brain. Somewhere between 8 and 10 months, most babies are working on several big skills at once:
Crawling, pulling to stand and cruising along furniture
Separation anxiety, which usually peaks around this age
Early language, understanding far more than they can say
Dropping from 3 naps to 2
All that practice doesn't switch off at bedtime. Your baby wakes between sleep cycles, remembers they can stand, and suddenly the crib is a gym. Unlike the 4 month sleep regression, which changes sleep for good, this one is mostly about new skills.
How long does the 8 month sleep regression last?
For most babies, 2 to 6 weeks. The length depends less on your baby and more on what habits get built while it's happening. If every wake-up turns into something new, like a 2 a.m. bottle, a trip to your bed or 40 minutes of rocking, your baby learns that's how nights work now. That's when a few rough weeks turn into a few rough months.
What schedule works best at 8 months?
Many babies are still on 3 naps at 8 months, and that third nap starts pushing bedtime too late. Most 8 month olds do well on 2 naps with wake windows of about 2.5 to 3.5 hours. A sample day:
| Time | What happens |
|---|---|
| 7:00 a.m. | Wake up |
| 9:45 to 11:00 a.m. | Nap 1 |
| 2:15 to 3:30 p.m. | Nap 2 |
| 6:30 p.m. | Bedtime routine |
| 7:00 p.m. | Asleep |
Standing in the crib every night for weeks?
The Restful Nights Plan gives you one clear way to respond, a schedule for this age and 14 days of daily support.
See the Restful Nights PlanIf your baby fights the third nap for more than a week, it's usually time to drop it and move bedtime a little earlier for a few days.
How do I help my baby practice new skills?
The fastest way through a skill regression is to let your baby master the skill while the sun is up. Give lots of floor time and help them practice:
Pulling to stand, then bending their knees to sit back down
Lowering themselves from standing while holding the couch
Crawling in and out of a small space
When your baby knows how to get down on their own, standing in the crib stops being a trap. If your baby is pulling to stand, lower the crib mattress to its lowest setting now.
How do I help with separation anxiety at night?
If your baby cries the second you leave, they're not manipulating you. They just figured out you exist when they can't see you, and they're not sure you'll come back.
Play peekaboo and hide and seek during the day
Always say goodnight before you leave; never sneak out
Keep a short, predictable bedtime routine
Spend 10 calm minutes of one-on-one time before the routine starts
What should I do at 2 a.m.?
Respond the same calm way every time, and try not to start something new just because it’s the quickest fix tonight, like a feed you had already dropped or bringing your baby into your bed. Babies learn fastest from consistency. How exactly to respond depends on your baby’s age, how they fall asleep and whether they still feed at night, and that’s where a personalized plan makes the difference.

When does the 8 month sleep regression start?
Usually somewhere between 8 and 10 months, often alongside crawling, pulling to stand or the switch to 2 naps.

Should I drop to 2 naps during the 8 month regression?
If your baby fights the third nap for more than a week or bedtime keeps getting pushed late, it's usually time to move to 2 naps.
Should I sleep train during the 8 month regression?
