A 10-month-old needs 12 to 16 hours of total sleep per day, including 9 to 12 hours at night and 2 to 3 hours spread across daytime naps. That’s a wide range, and where your baby falls within it depends on their individual temperament, nap quality, and how well they sleep overnight.
Nighttime Sleep at 10 Months
Most 10-month-olds are capable of sleeping 9 to 12 hours overnight, though not all of them do so without waking. By this age, many babies no longer need night feedings for nutrition. Breastfed babies may still wake for zero to two feeds per night, while formula-fed babies typically need zero to one. The key distinction is whether your baby is waking out of hunger or out of habit. If your baby is eating well during the day and gaining weight normally, overnight feeds are likely more of a comfort routine than a caloric necessity.
Most babies can get all the nutrition they need from daytime meals by around 6 to 10 months for breastfed infants and 4 to 6 months for formula-fed infants. That doesn’t mean you need to cut night feeds immediately, but it does mean that if overnight waking is a problem, hunger probably isn’t the root cause.
How Naps Should Look
At 10 months, your baby should be taking two naps per day: one in the morning and one in the afternoon. Together, those naps should add up to about 2 to 3 hours total. Each nap ideally lasts 60 to 120 minutes, though some babies consistently nap on the shorter end and make up for it with longer nighttime sleep.
If your baby is fighting the second nap or taking very short naps, it’s worth looking at their wake windows. At this age, babies generally do well with about 2 to 3 hours of awake time between sleep periods. Pushing too far past that window can backfire, making it harder, not easier, for your baby to fall asleep.
Spotting Tired Cues Before Overtiredness
A 10-month-old who’s ready for sleep will show it through behavior changes well before a full meltdown. Early signs include clinginess, fussiness with food, losing interest in toys, and becoming clumsy. You might also notice increased activity, which can be misleading. A baby who suddenly seems wired and hyperactive after being awake for a few hours is often overtired rather than energized.
Catching these cues early matters because an overtired baby is paradoxically harder to settle. Their stress hormones rise, they fight sleep more, and the sleep they do get tends to be lighter and shorter. If your baby is consistently difficult to put down, moving their nap or bedtime earlier by 15 to 30 minutes can make a noticeable difference.
The 10-Month Sleep Regression
If your baby was sleeping well and suddenly isn’t, you’re likely dealing with a sleep regression. At 9 to 10 months, several developmental changes converge to disrupt sleep.
Separation anxiety is a major factor. Your baby now understands object permanence, meaning they know you still exist when you leave the room. That’s a cognitive milestone, but it also means bedtime can trigger real distress about being apart from you. At the same time, many 10-month-olds are learning to crawl, pull up to standing, or cruise along furniture. These motor milestones are exciting, and babies often want to practice them at 2 a.m. instead of sleeping. Teething can also play a role, adding physical discomfort to the mix.
How long a regression lasts depends on what’s driving it. Teething pain typically resolves within a week. The novelty of a new motor skill usually wears off after a couple of weeks. But if you introduce new sleep habits during the regression, like rocking or feeding to sleep when you weren’t doing so before, the disruption can stretch into weeks or months. The regression itself is temporary; the habits you build around it may not be.
Putting It All Together
A realistic daily rhythm for a 10-month-old looks something like this: waking in the morning, staying awake for 2 to 3 hours, taking a morning nap of 1 to 2 hours, another 2 to 3 hour awake stretch, an afternoon nap of 1 to 2 hours, then a final awake period before bedtime. Most babies this age do well with a bedtime somewhere between 6:30 and 8:00 p.m., depending on when their last nap ended.
The total target is 12 to 16 hours in a 24-hour period. If your baby is consistently getting less than 12 hours and seems irritable, clumsy, or difficult to settle, they’re probably not getting enough. On the other hand, if they’re sleeping 13 hours and seem happy and alert during wake times, there’s no reason to push for more. The range exists because babies vary. What matters most is that your baby wakes rested, handles wake windows without falling apart, and is growing well.
