A 9-week-old baby's sleep schedule can vary, but it's important to remember that every baby is unique and their sleep patterns are still evolving. While there's no strict sleep schedule to follow yet, a 9-week-old baby may sleep anywhere from 11 to 19 hours in a 24-hour period, with 5 to 6 hours of uninterrupted sleep at night considered sleeping through the night. During the day, they may take 4 to 5 naps lasting between 10 minutes to 2 hours each, totalling 5 to 6 hours of daytime sleep. Bedtimes can be late, often after 9 pm, and are influenced by morning wake-up times and daytime sleep durations. It's normal for sleep to be fragmented, and parents should watch for their baby's sleepy cues and energy levels to determine if they need more sleep.

What You'll Learn

A 9-week-old baby's sleep schedule is unpredictable
At this age, a baby should be getting around 14-16 hours of sleep across a 24-hour period. However, the total amount of sleep for a 9-week-old baby in a 24-hour period could be anywhere from 11-19 hours. Their nighttime sleep could stretch to 4-6 hours, but it's normal for sleep to be fragmented, and not all babies are sleeping long stretches at night. Bedtimes at this age can be late, often after 9 pm, and will be determined by the morning wake-up time and sleep durations throughout the day.
A 9-week-old baby will usually take 4-5 naps per day, totaling 5-6 hours of daytime sleep. Wake windows are generally around 45 minutes to 1.75 hours, and we tend to see shorter awake periods in the morning, with the longest stretch of awake time during the day often right before bedtime. However, it's important to be responsive to your baby's sleepy cues, feeding needs, and nap lengths.
While milestones are based on ranges, every baby is different. If you have any concerns about your baby hitting their milestones, make sure to speak with your pediatrician.

Aim for 14-17 hours of sleep in a 24-hour period
At nine weeks old, a baby's sleep can still be quite unpredictable, and their sleep patterns are still evolving. While it's too early to follow a strict sleep schedule, you should aim for your baby to get around 14-17 hours of total sleep in a 24-hour period. This includes 5-6 hours of uninterrupted sleep at night, which is what is considered sleeping through the night for a baby, not the 8 or more hours that adults usually think of. During the day, they may get 5-6 hours of sleep split between 4-5 naps.
A baby's wake window is how long they stay awake between naps. At two months old, their wake windows might be shorter, around 45-90 minutes, and they will likely have a regular 24-hour cycle of eating and sleeping. It's important to be responsive to your baby's sleepy cues, feeding needs, and nap lengths. For example, if your baby isn't getting all their daytime calories, this could be why they're waking more during the night.
At nine weeks, your baby is becoming more alert and responsive to the world around them. They are gaining more control over their movements and may start to push up on their arms during tummy time. They are also starting to react to different noises, so it's a good time to take them to a baby class or group.
Remember that every baby is unique, and it's important to follow their lead and watch for their individual cues. Consult with healthcare professionals, such as your paediatrician or a lactation consultant, for guidance on night feedings and specific sleep advice.

Babies may sleep 5-6 hours at night
At nine weeks old, a baby's sleep schedule is likely to still be unpredictable, with sleep times and durations varying. A baby's sleep schedule should be flexible and based on their individual needs, such as their sleepy cues, feeding needs, and nap lengths. Wake windows—the length of time a baby stays awake between naps—for a two-month-old baby are typically around 45 minutes to 1.75 hours, with shorter awake periods in the morning and the longest stretch of awake time right before bedtime.
At this age, babies commonly take 4–5 naps per day, totaling 5–6 hours of daytime sleep. However, it's important to remember that every baby is unique, and some children have higher or lower sleep needs. Mood and energy levels can be good indicators that your baby is getting enough sleep.
As babies approach three months old, they may start to sleep through the night, which is typically considered a stretch of 5–6 hours without waking. Most babies start sleeping through the night by six months of age, and some may not sleep through the night until much older. It's recommended to consult with your child's pediatrician or a lactation consultant about your child's specific needs when it comes to night feedings.
To promote healthy sleep for your nine-week-old baby, follow their sleepy cues and try to establish a bedtime routine. Be patient and practice putting your baby down for naps or bedtime in their crib or bassinet while they are drowsy but still awake. This will help them learn to fall asleep on their own and create a healthy sleep foundation.

Late bedtimes are normal
At nine weeks old, a baby's sleep schedule will likely still be unpredictable. Sleep times and durations will vary, and this is normal. At this age, babies commonly take 4–5 naps per day, totalling 5–6 hours of daytime sleep. However, daytime sleep may last anywhere from 10 minutes to 2 hours, and this may change from nap to nap.
To establish a bedtime routine, start by practicing one nap each day in the crib. Follow your baby's sleepy cues and wake windows to ensure they go down for a nap or bedtime before getting cranky. Activities like tummy time and being outside can be stimulating for newborns and cause them to tire quickly. It's important to give yourself and your baby grace, as getting a 2-month-old to sleep in a crib or bassinet takes patience and practice.
Additionally, it's important to limit daytime naps to 1.5 to 2 hours at a time, especially if your baby is napping three times a day. Longer naps during the day can impact overnight sleep. By recognising your baby's sleepy cues and understanding their energy levels, you can determine if they've had enough awake time and are ready for sleep. Remember, every baby is unique, and their sleep schedule will depend on their individual needs.

Watch for sleepy cues
At nine weeks old, a baby's sleep schedule is likely to still be unpredictable, with sleep times and durations varying from day to day. This is normal, and it's important to remember that every baby is unique. While there is no recognised sleep regression at this age, it's also unlikely that your baby will be sleeping through the night.
To help you determine when your nine-week-old baby is ready for a nap, it's important to watch for their sleepy cues. A baby's wake window is how long they can stay awake between naps. At two months old, this is usually around 60 to 90 minutes, but it can be as little as 45 minutes or as long as 1 hour and 45 minutes.
- Your baby getting quiet
- Staring off into space
- Rubbing their eyes
- Yawning
- Looking away from you or losing interest in people and toys
- Sucking their thumb or fist
- Jerky, restless movements
- Fussing or crying
If you notice any of these sleepy cues, it's a good idea to start your baby's nap or bedtime routine. Following a flexible routine, rather than a rigid schedule, will help you work with your baby's unique developmental needs. Remember that activities like tummy time and being outside can be stimulating for newborns and cause them to tire quickly, so you may need to adjust their wake window and nap schedule accordingly.
