An 8-month-old typically needs 12 to 16 hours of total sleep in a 24-hour period. That breaks down to roughly 9 to 12 hours at night and about 3 hours of daytime naps. Where your baby falls in that range depends on their individual temperament, how well naps go, and whether developmental changes are disrupting their routine.
Nighttime Sleep at 8 Months
Most 8-month-olds can sleep a 9- to 12-hour stretch at night, though “stretch” doesn’t always mean uninterrupted. Night wakings are still common and normal at this age, especially for breastfed babies. Breast milk digests faster than formula, so breastfed infants often continue waking for at least one feeding through the night, and some don’t consistently sleep through until closer to their first birthday.
Even babies who had been sleeping through the night reliably may start waking again around this age. Separation anxiety peaks during the second half of the first year, and your baby may cry out when they realize you’re not in the room. This is a normal developmental stage, not a sign that something has gone wrong with their sleep habits.
How Naps Typically Look
Most 8-month-olds take two to three naps per day, adding up to about 3 hours of total daytime sleep. The first two naps should ideally last at least 60 minutes each. If your baby is still on a three-nap schedule, the third nap is usually a shorter catnap of 30 to 45 minutes.
Many babies transition from three naps to two somewhere around this age. You’ll know your baby is ready to drop the third nap when they consistently resist it, when it starts pushing bedtime too late, or when their first two naps have naturally lengthened enough to cover their daytime sleep needs. This transition can take a few weeks to settle, and some days will still call for a quick third nap to bridge the gap to bedtime.
Wake Windows Between Naps
At 8 months, most babies do well with roughly 2.5 to 3.5 hours of awake time between sleep periods. The first wake window of the day is usually the shortest, and the last one before bed is the longest. Getting these intervals right matters more than hitting a specific clock time for naps, because a baby who’s awake too long becomes overtired and fights sleep harder, while one who’s put down too soon simply won’t be tired enough to fall asleep.
The 8-Month Sleep Regression
If your baby’s sleep has suddenly fallen apart, you’re likely dealing with the 8-month sleep regression. This isn’t a medical problem. It’s a temporary disruption tied to the enormous developmental leap happening right now. Around this age, babies are learning to crawl, pull up to standing, sit independently, and process new cognitive skills like object permanence (understanding that you still exist when you leave the room). Teething often overlaps with this period too.
All of that new brain and body activity can cause restlessness at night. Your baby may practice pulling up in the crib, have trouble settling back down, or wake more frequently simply because their brain is busy processing new skills. Sleep regressions typically last two to six weeks. Keeping your routines consistent through this stretch helps your baby return to their normal patterns once the developmental burst settles.
What a Typical Day Looks Like
A sample schedule for an 8-month-old on two naps might look something like this:
- 6:30 a.m. Wake up, milk feeding
- 7:30 a.m. Breakfast (solids)
- 9:15 a.m. First nap (1 to 1.5 hours)
- 10:30 a.m. Milk feeding
- 11:30 a.m. Lunch (solids)
- 1:15 p.m. Second nap (1 to 2 hours)
- 3:15 p.m. Milk feeding
- 4:30 p.m. Dinner (solids, optional)
- 5:40 p.m. Last milk feeding
- 6:15 p.m. Asleep for the night
This is a framework, not a prescription. Your baby’s wake-up time, nap lengths, and hunger cues will shift the whole schedule earlier or later. The underlying structure to aim for is two solid naps, three to four milk feedings, two to three solid food meals, and a bedtime that falls roughly 12 hours before your target wake time.
Do Solid Foods Help Babies Sleep Longer?
Many parents hope that introducing more solid food will help their baby sleep through the night. The effect is minimal. One study on introducing solids earlier found that babies slept only about 16 extra minutes per night, a difference that’s barely noticeable in practice. Solids are important for nutrition and development at this age, but they’re not a reliable fix for night wakings. Hunger is only one of many reasons an 8-month-old wakes up; separation anxiety, teething discomfort, and developmental milestones play equally large roles.
Safe Sleep at 8 Months
By 8 months, your baby is likely rolling, sitting, and possibly crawling. Even so, the AAP recommends placing babies on their backs for every sleep, both naps and nighttime. If your baby rolls onto their stomach on their own during the night, that’s fine as long as the sleep surface is safe. What you can’t control once they’re mobile matters less than what you set up before you put them down.
The crib should have a firm, flat mattress with only a fitted sheet. No blankets, pillows, stuffed animals, bumper pads, or weighted sleepers. If you’re worried about warmth, dress your baby in one layer more than you’d wear in the same room. Signs of overheating include sweating and a chest that feels hot to the touch. Offering a pacifier at sleep times is also recommended, as it’s associated with a lower risk of sleep-related infant death.
Room sharing (keeping the crib in your bedroom) is recommended for at least the first six months. The AAP does not recommend bed sharing under any circumstances, even with older infants.
