Last Updated 11/18/2020
How much should a 4 month old sleep?
At this age most babies need at least 14.5 hours of total sleep in a 24 hour period.
If your baby’s still swaddled, please transition away from the swaddle for safety reasons. Also, with free hands and their increased motor control at this age, they may be able to use their hands or fingers to soothe.
This age is the perfect time to start shaping a baby's sleep habits in order to lay the foundation needed to ensure they become a great sleeper.

Nap time schedule for 4 month old
How long should a 4 month old nap?
At this age, we can expect to see 3.5-4.5 hours of day sleep. Try not to feel discouraged if you’re seeing a lot of short naps - it’s common to see shorter naps of 30-45 minutes.
The first nap or two of the day may start to lengthen around this time. We recommend limiting each individual nap to no more than 2 hours in order to ensure that day sleep does not interfere with nap sleep.
How many naps should a 4 month old take each day?
Most babies this age need 3-4 naps per day. Babies who are already taking longer naps can typically stay awake longer, so they tend to do well on a 3-nap schedule.
On the other hand, if a child takes shorter naps, they’ll get sleepier sooner. They'll likely need to follow a 4-nap schedule. Since naps can still be irregular at this age, it’s also common to see babies take some 3-nap days and some 4-nap days in the same week.

Bedtime for a 4 month old
What time should a 4 month old go to bed?
The appropriate bedtime depends on when your baby wakes up in the morning and how many naps they take. In other words, expect bedtime to still vary at this age. While the start of night sleep should remain somewhat flexible, earlier bedtimes between 6:00 PM - 8:00 PM are common. They can also ensure that your 4 month old gets enough sleep and remains well rested.
Now that your baby is 4 months old, they should be settling into a ~24 hour rhythm of sleeping and eating - thanks to a sufficient production of melatonin. While we don’t expect nap times or lengths to be entirely predictable yet either, we can focus on a regular wake up time which will help continue to regulate their schedule.
