8-month sleep & the 8–10 month regression

How much sleep an 8-month-old needs

By 8 months, total sleep usually lands in the broad range of about 12-16 hours per day, counting both night sleep and naps. Many babies this age take two naps. Some still take three, and a few are starting the slow move toward fewer naps.

These are ranges, not targets. A baby who sleeps a bit less or more and is generally content, feeding well, and growing is likely getting what they need. If you are unsure whether your baby is sleeping enough, ask your pediatrician, who can look at the full picture.

• Total sleep: about 12-16 hours in 24 hours, naps included
• Naps: often two, sometimes three
• Night sleep makes up the largest single block

Why the 8-10 month regression happens

Around this age babies are working hard on new skills. Many are sitting, crawling, pulling to stand, and babbling, and they often practice these skills at night or at the edges of naps. Separation awareness also grows, so your baby may protest more when you leave the room.

All of this can lead to more night wakings, shorter naps, or harder bedtimes for a few weeks. It is a developmental phase, not a permanent change. Sleep usually settles again as the new skills become routine.

What you can do

Keep your routine steady. A predictable, calm wind-down and consistent sleep times give your baby a clear signal that sleep is coming. Give your baby a chance to practice new skills during the day, which can reduce nighttime practice sessions.

When your baby wakes at night, keep your response low-key. Reassure briefly with a calm voice or a gentle touch, and give them room to resettle when they can. Aim to keep the room dark and quiet so it stays clearly different from daytime.

• Hold a consistent bedtime and nap schedule
• Use a short, repeatable wind-down routine
• Allow daytime time for sitting, crawling, and standing practice
• Respond calmly and briefly to night wakings

Keeping sleep safe

Safe sleep still matters at 8 months, even as your baby becomes more mobile. Place your baby on their back to sleep on a firm, flat surface made for infants. Keep the sleep space clear of soft bedding, pillows, bumpers, and toys.

If your baby rolls or moves into a new position on their own during sleep, you do not need to reposition them. Continue to start every sleep on the back. If you have questions about your baby's sleep setup, your pediatrician can help.

Quick answers

Is the 8-10 month sleep regression normal?

Yes. More night wakings, shorter naps, or harder bedtimes around 8-10 months are common and usually tied to fast development, such as crawling, pulling to stand, and growing separation awareness. It is typically temporary and tends to settle as the new skills become familiar. If you are worried or it lasts a long time, talk with your pediatrician.

How many naps should my 8-month-old take?

Many 8-month-olds take two naps, while some still take three and a few are moving toward fewer. There is no single right number. Watch your baby's overall mood, feeding, and total daily sleep rather than a fixed nap count, and check with your pediatrician if you have concerns.

Should I feed my baby every time they wake at night during this phase?

Not necessarily. Some night wakings during this phase are about practicing new skills or wanting reassurance rather than hunger. You can respond calmly and briefly and give your baby a chance to resettle. Your pediatrician can advise on whether your baby still needs night feedings based on age, weight, and growth.
