Most 10-month-olds need about 13.5 to 14 hours of total sleep in a 24-hour period, split between 11 to 12 hours overnight and roughly 2 to 2.5 hours of daytime napping. If your baby is fighting bedtime, waking frequently, or refusing to nap, the fix usually involves some combination of routine, timing, environment, and how you respond when they cry out. Here’s what actually works at this age.
Why 10 Months Is Uniquely Difficult
This age is a perfect storm for sleep disruption. Your baby is likely dealing with separation anxiety, a normal developmental phase where they become distressed when you leave the room. That’s why many 10-month-olds cry out in the middle of the night and then calm down the moment a parent walks in. They’re not hungry or in pain. They just want to confirm you’re still there.
On top of that, teething may be in full swing. Each teething episode lasts about 3 to 8 days and causes mild fussiness, drooling, and gum sensitivity. It can nudge your baby’s temperature slightly above normal (up to about 100.3°F), but it doesn’t cause true fevers, vomiting, diarrhea, or persistent coughing. If you’re seeing those symptoms, something else is going on. Ear pulling can also signal an ear infection rather than teething, so don’t assume teeth are always the explanation.
Knowing whether the disruption is developmental, physical, or habit-based helps you choose the right response instead of guessing in the dark at 2 a.m.
Build a 30 to 45 Minute Bedtime Routine
A consistent bedtime routine is the single most reliable tool for signaling sleep. Aim for 30 to 45 minutes of the same activities in the same order every night. The specific steps matter less than the consistency, but certain elements have a physiological basis worth using.
A warm bath, for instance, does more than just relax your baby emotionally. It stimulates blood flow to the hands and feet, which triggers a cooling of the body’s core temperature afterward. That drop in core temperature is the same pattern the body follows naturally when falling asleep, so a bath essentially jumpstarts the process. Follow the bath with pajamas, a feeding about 15 minutes before you place your baby in the crib, a book or a song, and then into the crib while they’re drowsy but still awake.
That last part, putting them down drowsy but not fully asleep, is the key skill. Babies who fall asleep in your arms and then wake up in a crib often panic because their environment changed without their awareness. A baby who falls asleep in the crib learns to recognize that space as where sleep happens, and they can resettle themselves when they wake between sleep cycles overnight.
Get the Wake Windows Right
At 10 months, most babies do best on two naps a day with wake windows of about 2.5 to 3.5 hours between sleep periods. That means if your baby wakes at 7 a.m., the first nap falls around 9:30 to 10:00 a.m. and should last 1 to 2 hours. The second nap comes about 3 hours after the first one ends, lasting 1 to 1.5 hours.
Watch your baby’s tired signs closely: rubbing eyes, pulling ears, staring into space, getting clumsy. Putting a baby down too early means they’re not tired enough to fall asleep easily. Putting them down too late means they’re overtired, which floods the body with stress hormones and paradoxically makes it harder to fall asleep. Overtiredness is one of the most common reasons 10-month-olds fight bedtime, and it usually traces back to a nap that was too short or too early in the day.
If the second nap ends by 3:00 p.m. and bedtime is 7:00 p.m., that final wake window of about 4 hours is typical for this age. You want enough sleep pressure built up that your baby is genuinely ready to sleep for the long stretch.
Set Up the Room for Sleep
Keep the nursery between 68°F and 70°F (20°C to 21°C). Babies sleep best in a slightly cool room, and overheating is both a comfort issue and a safety concern. Dress your baby in a sleep sack appropriate for the room temperature rather than using loose blankets.
The American Academy of Pediatrics recommends keeping loose blankets, pillows, stuffed toys, bumpers, and other soft items out of the crib entirely. At 10 months, your baby is mobile enough to roll into soft objects, and the risk remains real. A firm mattress with a fitted sheet and a wearable blanket is all you need.
Darkness matters more than most parents expect. Even small amounts of light can suppress the sleep hormone that helps your baby stay asleep. Blackout curtains or shades make a noticeable difference, especially for early morning wake-ups when sunlight creeps in. White noise can also help mask household sounds and create a consistent auditory cue that it’s time to sleep.
Handle Night Wakings Strategically
If your 10-month-old wakes and cries at night, pause before rushing in. Many babies fuss for a minute or two and then resettle on their own. When you respond instantly every time, you can inadvertently teach your baby that crying brings you back, which reinforces the waking.
When you do go in, keep it boring. Don’t turn on lights, don’t pick them up if you can avoid it, and don’t start playing or talking animatedly. A brief pat, a quiet “shh,” and then leaving again teaches your baby that nighttime is for sleeping and that you’re nearby but not there to entertain.
For formula-fed babies over 6 months, nighttime hunger is rarely the reason for waking. Formula digests slowly enough that a well-fed 10-month-old can go through the night without a feed. For breastfed babies, night weaning is generally appropriate starting around 12 months, when most children are getting enough daytime calories for growth. Before that, some breastfed 10-month-olds may still genuinely need one overnight feed, and that’s normal. If you’re unsure whether your baby’s night wakings are hunger-driven, tracking whether they take a full feed or just comfort-nurse for a minute can help you tell the difference.
Sleep Training at 10 Months
If your baby cannot fall asleep without being held, rocked, or fed to sleep, you’re dealing with a sleep association that requires your presence. Sleep training is the process of teaching your baby to fall asleep independently, and 10 months is a reasonable age to start.
The graduated method (sometimes called the Ferber method) involves putting your baby down awake, leaving the room, and returning at increasing intervals to briefly reassure them without picking them up. You might check in after 3 minutes, then 5, then 10, gradually stretching the time. This approach typically takes 7 to 10 days to show clear results, with the most crying happening in the first 2 to 3 nights.
Some parents prefer a more gradual approach: sitting in a chair next to the crib and moving the chair farther from the crib every few nights until you’re outside the room. This takes longer but involves less crying. Others prefer to simply stay consistent with their bedtime routine and let the baby work it out, checking in at set intervals. No single method works for every family, and the “best” method is the one you can stick with consistently. Inconsistency, where you sometimes give in and sometimes don’t, is what drags the process out and creates more distress for everyone.
When Teething Disrupts Everything
Teething pain peaks in the days just before and after a tooth breaks through, and the disruption typically lasts 3 to 8 days per tooth. During an active teething episode, your baby may genuinely need more comfort at night, and that’s fine. Offering a chilled teething ring before bed or gently rubbing the gums can help ease discomfort before you start the bedtime routine.
The important thing is returning to your normal routine and expectations once the episode passes. A week of extra comfort during teething won’t undo months of good sleep habits, but two or three weeks of new habits (rocking to sleep, co-sleeping, feeding to sleep) absolutely can. Give yourself permission to be flexible during genuine discomfort, and then reset.
What a Realistic Schedule Looks Like
- 6:30–7:00 a.m.: Wake up and first feed
- 9:30–10:00 a.m.: First nap (1 to 2 hours)
- 2:00–2:30 p.m.: Second nap (1 to 1.5 hours)
- 6:15–6:30 p.m.: Start bedtime routine (bath, feed, book)
- 7:00–7:30 p.m.: In the crib, drowsy but awake
This is a template, not a prescription. Your baby’s ideal times will depend on when they naturally wake, how long their naps run, and their individual sleep needs. The principle to follow is consistent wake windows of 2.5 to 3.5 hours, two naps totaling about 2 to 2.5 hours, and a bedtime that allows for 11 to 12 hours of overnight sleep. If your baby consistently takes 20 minutes to fall asleep or wakes very early in the morning, the schedule may need shifting by 15 to 30 minutes in one direction.
