Most 8-month-old babies need 12 to 16 hours of total sleep per 24-hour period, split between nighttime sleep and daytime naps. That’s a wide range, and where your baby falls depends on their nap schedule, how well they sleep at night, and whether developmental changes are temporarily throwing things off.
Total Sleep and How It Breaks Down
At 8 months, the bulk of your baby’s sleep happens at night, typically 10 to 12 hours, with the remaining 2 to 3 hours spread across daytime naps. Most babies this age take two to three naps per day. The first two naps are usually the longest, ideally at least 60 minutes each. If your baby still takes a third nap, it’s generally a shorter catnap of about 30 to 45 minutes.
It’s completely normal for your baby to have a mix of two-nap and three-nap days during this period. Eight months is a transitional age, and many babies are in the process of dropping that third nap entirely.
Signs Your Baby Is Ready for Two Naps
The shift from three naps to two is one of the bigger schedule changes in the first year, and it commonly happens between 6.5 and 8 months. Your baby may be ready if they start showing several of these patterns:
- Trouble falling asleep at nap time or bedtime
- New night wakings that weren’t happening before
- Regularly refusing or protesting a nap
- Consistently short naps
- Needing a bedtime pushed past 8:00 PM to fit the third nap in
- Waking before 6:00 AM when that wasn’t typical
If you’re seeing just one of these signs on occasion, it could be a rough day rather than a true transition. But if several of these patterns persist for a week or two, it’s probably time to consolidate to two longer naps and move bedtime a bit earlier to compensate.
The 8-Month Sleep Regression
If your baby was sleeping well and suddenly isn’t, you’re likely dealing with what’s commonly called the 8-month sleep regression. It’s not a step backward in development. It’s the opposite: so much is changing in your baby’s brain and body that sleep temporarily takes a hit.
Several things converge around this age to disrupt sleep. Teething can cause fussiness and wake-ups. Separation anxiety, which typically begins ramping up around 9 months, may start appearing now and make your baby protest being put down alone. Greater awareness of their environment means more stimulation to process. And new physical skills, like crawling and pulling to stand, can cause restlessness at night. Research tracking infants from 5 to 11 months found that the onset of crawling was temporally linked to increased periods of disrupted sleep, even as overall sleep consolidation improved over time.
The good news: sleep regressions at this age are normally short-lived. Most pass within a few weeks without any major intervention, as long as you stay reasonably consistent with your baby’s routine.
Night Feedings at 8 Months
Whether your baby still needs to eat at night depends partly on how they’re fed. Formula-fed babies over 6 months are unlikely to be waking from genuine hunger, since formula digests more slowly and most are getting sufficient calories during the day. For breastfed babies, the picture is a bit different. Night feeds before 12 months help maintain milk supply, and many breastfed babies continue to wake for feeds and comfort throughout the first year. That’s normal, not a problem to solve.
If your baby wakes at night but isn’t hungry, they may be looking for comfort or practicing new skills. Babies who have just learned to pull themselves up, for instance, sometimes get stuck standing in the crib and need help lying back down.
Setting Up the Room for Better Sleep
Room environment plays a real role in sleep quality. Keep the nursery between 68 and 78 degrees Fahrenheit. A simple rule of thumb: if the temperature feels comfortable to you, it’s likely fine for your baby. A fan set on low helps with air circulation and also provides consistent background noise, which can help smooth the transitions between sleep cycles.
At 8 months, babies are increasingly aware of light and activity around them. A dark room with minimal stimulation signals that it’s time to sleep, which becomes more important as their environmental awareness grows. If your baby is fighting sleep at bedtime, overstimulation in the hour before bed is one of the first things worth adjusting.
What a Typical Day Looks Like
There’s no single perfect schedule, but a common pattern for an 8-month-old on two naps looks something like this: wake around 6:00 to 7:00 AM, first nap mid-morning for about an hour, second nap early afternoon for about an hour, and bedtime between 7:00 and 8:00 PM. Babies still on three naps will have a shorter afternoon catnap squeezed in, with bedtime pushed slightly later.
The spacing between sleep periods matters more than the clock times. Most 8-month-olds can handle about 2.5 to 3.5 hours of awake time between naps. If wake windows stretch too long, your baby can become overtired, which paradoxically makes it harder for them to fall asleep and stay asleep. If you notice your baby getting fussy, rubbing their eyes, or zoning out, they’re likely signaling that their wake window is closing.
