An 8-month-old typically needs 12 to 16 hours of total sleep in a 24-hour period. That breaks down to roughly 11 hours at night and about 3 hours of daytime naps. Every baby is different, but if your 8-month-old is consistently landing in that range, their sleep is on track.
Nighttime Sleep and Naps
Most of your baby’s sleep should happen overnight in one long stretch, ideally around 10 to 12 hours. Some babies sleep through the night at this age, while others still wake once or twice.
During the day, aim for about 3 hours of total nap time split across 2 to 3 naps. Most 8-month-olds are in the process of transitioning from three naps down to two. If your baby is still taking three naps, the first two should each be at least 60 minutes, while the third is a shorter catnap of 30 to 45 minutes. Once they drop to two naps, those two naps tend to be longer and more predictable.
Wake Windows Between Naps
At 8 months, babies do best staying awake for about 2 hours and 45 minutes to 3 hours and 30 minutes between sleep periods. These stretches of awake time, sometimes called wake windows, tend to get a little longer as the day goes on. So the gap between morning wake-up and the first nap might be closer to 2 hours 45 minutes, while the window before bedtime can stretch to 3 and a half hours.
Watching for your baby’s sleepy cues within these windows matters more than watching the clock. Rubbing eyes, yawning, fussiness, and staring off into space are all signs your baby is ready for sleep. Pushing past that window often makes it harder for them to settle, not easier.
The 8-Month Sleep Regression
If your baby was sleeping well and suddenly isn’t, you’re likely dealing with the 8-month sleep regression. This is one of the more common rough patches in the first year, and it’s driven by a burst of physical and cognitive development happening all at once.
Around this age, many babies are learning to crawl, pull to stand, and sit up on their own. Their brains are also making leaps in awareness: they understand more about their environment, recognize familiar faces more sharply, and start developing stronger emotional attachments. That last one is key, because it fuels separation anxiety. Your baby may cry out when you leave the room at bedtime or wake in the middle of the night and need to see you before settling back down. Teething can pile on top of all this, adding discomfort that disrupts sleep further.
Sleep regressions typically last 2 to 6 weeks. They feel long in the moment, but they do pass. Staying consistent with your routines during this stretch helps your baby return to normal sleep patterns faster once the developmental leap settles.
Night Feedings at 8 Months
By 8 months, most babies can get enough calories during the day that they don’t need multiple overnight feeds. If your baby is waking to eat more than twice a night, that pattern is likely driven by habit rather than hunger. Many pediatric guidelines suggest that by 4 to 6 months, babies are capable of going 5 or more hours between nighttime feedings, and by 8 months, some babies drop night feeds entirely.
That said, growth spurts, teething, and routine changes can temporarily increase nighttime hunger. If your baby has recently started crawling or become more active during the day, a short-term uptick in feeds isn’t unusual. The key is whether the pattern persists or resolves on its own within a week or two.
Sleep Training Options
Eight months is a fine age for sleep training if your baby hasn’t learned to fall asleep independently yet. Most babies are developmentally ready for sleep training by about 4 months, so at 8 months your baby has the self-soothing capacity to learn this skill. The common approaches fall along a spectrum from less to more parental involvement.
On one end, the cry-it-out method involves putting your baby down awake, saying goodnight, and not returning until morning or the next scheduled feed. It’s the fastest approach but the hardest emotionally for parents. The Ferber method softens this by letting you check in at timed intervals, gradually stretching those intervals longer over several nights. You go in, briefly reassure your baby without picking them up, and leave again.
On the gentler end, the chair method has you sitting in a chair next to the crib until your baby falls asleep, then moving the chair farther away every few nights until you’re out of the room entirely. The pick-up, put-down method lets you physically comfort your baby by lifting them when they cry, calming them, then placing them back in the crib. Bedtime fading works differently: it shifts your baby’s bedtime gradually, in 15-minute increments, to match their natural drowsiness.
No single method works best for every family. What matters most is consistency. Switching between methods or giving up after two nights tends to prolong the process and confuse your baby.
Building a Bedtime Routine
A predictable bedtime routine signals to your baby that sleep is coming. At 8 months, this doesn’t need to be complicated: a bath, a change into pajamas, a feed, a book or quiet song, and then into the crib drowsy but awake. The whole sequence can take 20 to 30 minutes.
Because separation anxiety peaks during this period, your baby may protest more at bedtime than they used to. This is normal and developmental, not a sign that something is wrong. Keeping the routine calm and consistent, even when your baby fusses, helps them build the association between these steps and falling asleep. Over time, the routine itself becomes reassuring enough that the protests fade.
Bedtime for most 8-month-olds falls somewhere between 6:30 and 8:00 PM, depending on when their last nap ended. If the final wake window before bed runs about 3 to 3.5 hours and their last nap ended around 4:00 or 4:30 PM, a bedtime around 7:00 to 7:30 PM works for most families.
