The short answer
Babies aged 7–9 months are generally advised to get 12–16 hours of sleep per 24 hours, including naps. This comes from the American Academy of Sleep Medicine recommendation for babies aged 4–12 months. Your baby does not have to sleep the same hours or take the same number of naps as every other baby.

Keep in mind
- A general reference for babies aged 7–9 months is 12–16 total hours per 24 hours, including naps.
- Consider total sleep and daytime well-being rather than a required number of nighttime hours.
- Two or three naps may occur; there is no single correct month to drop the third.
- Persistent snoring, breathing problems, difficulty waking, or affected feeding and growth warrant assessment.
How should you think about total sleep at 7–9 months?
When your baby wakes at 6 a.m., you might feel that their night was too short. But once you count their morning and afternoon naps, the picture can look very different. At this age, looking at total sleep over 24 hours is more useful than focusing on one night.
The American Academy of Sleep Medicine (AASM) recommends 12–16 hours of sleep in 24 hours, including naps, for babies aged 4–12 months. The CDC uses the same range. This is not a race to hit an average; it is a general guide to help you understand your baby's patterns over several days.
Do 7-, 8- and 9-month-olds need different hours?
There aren't separate mandatory targets of 13 hours at 7 months, 14 at 8 months, and 12 at 9 months. Just as children the same age can have different sleep needs, your baby's pattern may change across these three months.
Your 7-month-old might take three short naps. At 8 months, they may be comfortable with two longer naps; a 9-month-old may still need a brief third one. You don't have to reorganize the day just because the calendar changes.
How much sleep should be at night versus daytime?
The 12–16-hour recommendation covers nights and naps together. Guidelines do not require every 7–9-month-old to sleep a fixed number of hours at night or nap for an exact number of minutes. For example, 10 hours at night plus 3 hours of naps equals 13 hours. That's an illustration of adding up sleep, not a schedule to follow.
When nighttime sleep increases, naps may shorten, or the opposite may happen on some days. How rested your baby seems, how they feed, and how they interact also matters alongside the numbers.
Two naps or three?
Nap frequency can vary during these months. Your baby might take a short morning nap, another in the afternoon, and a brief rest toward evening. Over time, interest in that last nap may fade as the first two naps lengthen.
If you're considering dropping a third nap, watch more than your baby's age: notice evening tiredness and whether bedtime becomes difficult. Keeping an overtired baby awake doesn't guarantee better sleep. The goal isn't compliance with a chart but opportunities to rest throughout the day.
Do night wakings mean your baby is not sleeping enough?
Waking briefly overnight doesn't necessarily mean your baby had too little sleep that day. At this age they may look for you, want to feed, or need help settling again. Separation anxiety during the second half of the first year can affect sleep for some babies.
Along with how often your baby wakes, notice how they seem afterward. Ongoing distress, feeding difficulties, or marked daytime tiredness shouldn't automatically be labeled a ‘sleep regression.’ Don't decide to end night feeds based on age alone; discuss feeding and growth with your pediatrician.
How can you tell when your baby needs sleep?
Sometimes your baby loses interest in a favorite toy, rubs their eyes, or settles more easily in your arms. Sometimes their movements become more intense just before they cry. These signals vary from baby to baby; watching over several days helps you learn your baby's rhythm.
After sleep, eye contact, interest in play, and seeming generally comfortable can be helpful observations too. Look for recurring patterns over different days rather than judging one difficult evening.
What can you do today?
If you like, jot down your baby's morning wake-up, approximate nap start and end times, and bedtime for three days. It may help you see a total-sleep pattern instead of anxiously checking the clock every night. You don't need to calculate every minute of brief awakenings perfectly.
Dimming the lights, singing a gentle lullaby, and repeating a familiar bedtime sequence may help make sleep predictable. A routine that fits your family and is sustainable is enough; no minute-by-minute timetable is required.
What about safety, regardless of sleep duration?
Even if your baby rolls and moves in the crib, always place them on their back at the start of sleep. Use a firm, flat, non-inclined sleep surface without pillows, loose blankets, stuffed toys, or positioning devices. If they roll independently and comfortably both ways, they can remain in a position they move into themselves.
Don't use a car seat, swing, or inclined seat for routine sleep. Starting sleep safely is a separate concern from sleep duration, but just as important.
When should you talk to your pediatrician?
Contact your pediatrician if sleep has been markedly reduced for some time, your baby seems constantly exhausted during the day, or waking affects feeding or growth. Frequent loud snoring or suspected pauses in breathing during sleep also need assessment.
If your baby is difficult to wake, unusually unresponsive, or struggling to breathe, don't simply monitor the sleep schedule: seek emergency help. Hours of sleep alone cannot establish a diagnosis; your baby's overall condition needs wider consideration.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- Seek emergency help if your baby is hard to wake, unusually unresponsive, or struggling to breathe.
- Contact your pediatrician for repeated loud snoring, suspected pauses in breathing, prolonged sleep problems, or affected feeding and growth.
