4 Month Old Sleep Schedule and Development
Nov 28 2019
4 Month Old Sleep Development:
At this age most babies need at least 14.5 hours of total sleep in a 24 hour period. We recommend aiming for 10-11 hours of sleep at night and 3.5-4.5 hours of day sleep (split into 3-4 naps).
4 month olds 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, we can focus on a regular wake up time which will help continue to regulate their schedule.
The amount of awake time between naps will become longer: most babies this age need between 1.5 - 2.5 hours of wakefulness before they are ready for sleep again. 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.
Let’s take a look at an example of a 4 Month Old's sleep schedule:
Note: Sleep needs vary by child and this chart should be viewed as an example.
If your baby’s still swaddled, you’ll want to start thinking about transitioning away from the swaddle before they start to roll for safety reasons.
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.
