With over 15 years of experience as a pediatric sleep consultant, I’m happy to share sample 4 month old sleep schedules with feedings. These sample schedules include milk feedings for breastfeeding and formula-feeding babies, solids, naps, and nighttime sleep.
4 Month Old Baby’s Sleep and Development
Pediatricians disagree high and low about when a baby is capable of sleeping through the night and only a handful of parents who reach this page will have a 4 month old who sleeps all night without even a single feeding (those that do are LUCKY!).
Most 4-month-olds need 11-12 hours at night and 3-4 hours during the day. And, many 4-month-olds are still eating 1-2 times a night and some naps are just 30 minutes. In addition, most 4 month olds will take 4 naps a day. Consequently, short naps are normal development at this age as it’s highly unusual for babies to take four 1-hour naps.
At this age, if you are not lucky enough to have a baby who sleeps through the night, many 4-month-olds are still waking 1-3 times to eat at night and many breastfeeding babies will continue to eat 1-2 times until 9+ months of age. On the other hand, formula-fed babies will often be night-weaned by 6 months old. More night feedings than that and likely you have a sleep association problem.
How Many Naps for a 4 Month Old?
Most 4-month-old babies take 4 naps each day totaling 3-4 hours of sleep. The reason for so many naps is primarily because babies this age can’t stay awake longer than 1-2 hours at a time. 4 month old wake windows are still short. Therefore, t’s still common to spread out daytime sleep among multiple sleep periods. However, some babies this age can stay awake longer and drop the fourth nap transitioning to a 3-nap schedule early.
4 Month Old Wake Windows
The typical 4-month old wake window is 1 to 2 hours with the first wake window being one of the shortest. Sometimes, that first wake window is just 75 to 90 minutes.
When Your 4 Month Old’s Sleep Gets Worse
If your baby has recently started sleeping worse, you may want to read more about 4 month old baby sleep. Keep in mind that one of the biggest sleep challenges families face around 4 months is the 4 month sleep regression. During this time period, babies change their sleep permanently and will wake up frequently at night and take shorter naps.
Obviously, all babies vary, but here are some sample (loose) schedules you can use to make your own for your unique baby. Most babies, at this age, can’t be on a strict schedule because many babies are still taking shorter naps while their brain matures and they simply can not stay up very long to get to the next scheduled nap-time. So, at this age, it’s likely naps are still on the short side, but come frequently and every day will still likely be different.
Don’t worry, that will change!

4 Month Old Feeding
Breast milk or formula should be the primary nutrition for the first year and solids come secondary. Below are the amounts we recommend if your pediatrician recommends solids before 6 months, the age at which most are recommending now. For more information on starting your baby on solid food, we have a series of blog posts dedicated to the subject. We include recommendations about how and when to start solids, as well as helpful information on food allergies, recommended products, baby-friendly recipes, and more.
Average amounts per day:
• At least 5-6 breastfeeding sessions per day or 2 1/2 ounces formula for each pound of weight (approx. 20-30 ounces) (decrease solids if your baby is not taking in at least this much)
• Water is unnecessary (breast milk and formula have plenty of water in them).
And, ONLY IF your pediatrician recommends solids this young (it is now recommend at 6+ months):
• Up to 1-2 servings baby cereal (1 serving = 1-2 Tablespoons dry)
• Up to 1-2 servings fruit or veggies (1 serving = 1-2 Tablespoons)
Note: With your doctor’s approval and guidance, you will start with just one teaspoon of solids (before mixing w/ breast milk or formula) and work your way up. Don’t forget to wait at least 3-4 days before introducing a new food for food allergy reasons.
“Thank you for your articles, they’ve shown me that my 4 month old baby is perfectly normal and I’m doing the right things in relation to his sleep. This is such a relief! So many sources just don’t seem to give realistic information about baby sleep – not for myself or for any other mum I know.
Great care has obviously been taken by The Baby Sleep Site in reflecting a realistic and true picture of what a ‘normal’ baby is. Thank you.”
This schedule assumes a baby can stay up 1 hour 15 minutes before needing to sleep again. At this age, wake-time should be 1-2 hours TOPS, to avoid baby getting overtired.
|4-Month-Old Sleep Schedule|
|6:30 AM||Wake and Breast milk or Formula|
|7:15 AM||Solids (Only if your pediatrician has recommended starting this early)|
|8:15-8:45||Breast milk or Formula|
|10:45-11:15||Breast milk or Formula|
|1:15-1:45||Breast milk or Formula|
|3:45-4:15||Breast milk or Formula|
|5:45||Begin bedtime routine|
|6:00||Breast milk or Formula|
|6:15||Bedtime (Goal to be asleep at this time)|
+Plus probably 1-3 nighttime feedings
Note: This schedule follows the eat-play-sleep routine, however, it is sometimes hard to do at this age when the amount of time between naps is not long enough and your baby wakes too early from his nap because of a feeding.
