A 6-month-old needs roughly 13 to 15 hours of total sleep per day, split between nighttime sleep and daytime naps. Most babies this age sleep about 10 to 11 hours at night and take two to three naps during the day, each lasting one to two hours.
Nighttime Sleep at 6 Months
At this age, your baby is capable of longer stretches of nighttime sleep than they were just a few months ago. Most 6-month-olds sleep 10 to 11 hours overnight, though not all of that will necessarily be uninterrupted. Some babies sleep through the night by now, while others still wake once or twice.
The good news is that nighttime feedings are no longer a nutritional necessity for most 6-month-olds. UCSF Benioff Children’s Hospitals notes that babies at this age don’t need nighttime calories to grow properly. Most who still wake to eat are doing so out of habit rather than hunger. That doesn’t mean you need to cut night feeds immediately, but it’s helpful to know the difference between a baby who’s hungry and one who’s looking for comfort to fall back asleep.
How Many Naps and How Long Between Them
Most 6-month-olds take three naps a day, with each lasting one to two hours (the third nap is often shorter, sometimes just 30 to 45 minutes). Some babies start dropping to two naps around this age, especially if they’re handling longer stretches of awake time well.
The time your baby can comfortably stay awake between naps, often called a “wake window,” is typically around 2 to 3 hours at 6 months. The first window of the day is usually the shortest (around 2 hours after waking), with each subsequent one stretching slightly longer. A common pattern for a 3-nap day looks something like 2 hours awake, then a nap, then 2.5 hours awake, another nap, 2.5 hours awake, a short nap, and finally about 3 hours awake before bedtime.
If your baby is transitioning to two naps, those wake windows spread out to roughly 3 hours between the first two sleeps and closer to 4 hours before bed. You’ll know the transition is happening when your baby consistently fights or skips that third nap without becoming overtired by bedtime.
Why Sleep Can Fall Apart at 6 Months
Even babies who were sleeping well may hit a rough patch around this age. Two big developmental shifts are happening at once. First, your baby is learning to sit up and may be starting early attempts at crawling. All that new physical activity can leave their brain buzzing at bedtime, making it harder to settle.
Second, babies between 6 and 9 months begin developing object permanence, the understanding that things (and people) still exist when they’re out of sight. This is a significant cognitive leap, but it also means your baby now realizes you’ve left the room. That awareness can trigger more frequent wake-ups and protests at bedtime, sometimes called the 6-month sleep regression.
Sleep regressions are temporary. They typically last two to four weeks. Sticking to a consistent routine during this stretch helps your baby adjust to their new skills without building sleep habits you’ll need to undo later.
How Solid Foods Affect Sleep
Six months is when most families start introducing solid foods, and there’s real evidence this can modestly improve sleep. A study from King’s College London followed over 1,300 infants and found that babies who had been introduced to solids earlier slept about 16 minutes longer per night and woke less frequently compared to babies who were exclusively breastfed. The differences peaked right around 6 months.
Sixteen minutes might not sound like much, but it adds up to nearly two extra hours of sleep per week. The researchers also found that parents in the solids group reported fewer sleep problems overall, which correlated with better maternal quality of life. Starting solids won’t magically produce a baby who sleeps 12 hours straight, but it can be one piece of the puzzle as your baby’s sleep matures.
Sleep Training at 6 Months
Six months is widely considered a developmentally appropriate time to start sleep training if you choose to. The goal is teaching your baby to fall asleep independently, so that when they naturally wake between sleep cycles at night, they can drift back off without needing you to intervene.
There are several approaches, and all of them can be effective:
- Gradual retreat (chair method): You sit near the crib until your baby falls asleep, then move your chair a little farther away each night until you’re out of the room. This works well for parents who want to stay present but reduce hands-on soothing over time.
- Gentle or “no tears” methods: These rely heavily on a consistent bedtime routine and aim to help your baby learn to self-soothe without extended crying. The process is slower but feels more comfortable for some families.
- Graduated extinction (Ferber method): You leave the room and check in at gradually increasing intervals, offering brief reassurance without picking your baby up. Most families see results within a week.
- Full extinction (cry it out): You put your baby down awake and don’t return until morning (or a scheduled feed). It’s the fastest method but involves more crying upfront.
No single method is superior. The best one is whichever you can follow through on consistently, because inconsistency is what tends to drag the process out and create more frustration for everyone.
Safe Sleep Reminders
The American Academy of Pediatrics guidelines still apply at 6 months. Place your baby on their back in their own sleep space, whether that’s a crib, bassinet, or portable play yard. The mattress should be firm and flat with only a fitted sheet on it. Keep blankets, pillows, stuffed animals, and crib bumpers out of the sleep area. Avoid letting your baby sleep on couches, armchairs, or in swings and car seats (outside of the car).
Some 6-month-olds roll onto their stomachs during sleep. If your baby can roll both ways on their own, you don’t need to keep flipping them back. Just make sure you always place them on their back initially and that the sleep surface is clear of anything soft they could press their face into.
Signs Your Baby Is Getting Enough Sleep
Total sleep recommendations are averages, and individual babies vary. Rather than fixating on exact hours, look at how your baby behaves during their awake time. A well-rested 6-month-old is generally alert, engaged, and able to play happily for reasonable stretches. An overtired baby tends to be fussy, difficult to soothe, and paradoxically harder to get to sleep.
If your baby consistently falls asleep within 10 to 20 minutes at nap time and bedtime, wakes up in a decent mood, and isn’t melting down well before the next scheduled nap, their sleep quantity is likely in a good range. Babies who fight every nap, take only 20-minute catnaps, or seem wired and cranky by late afternoon may need an adjustment to their schedule, whether that means tweaking wake windows, shifting bedtime earlier, or adding a short bridge nap to get through the day.
