What’s often happening this month
Moving from three naps to two
The third, late-afternoon nap often drops around this stage. Days can feel uneven during the switch — flexible timings and an earlier bedtime on harder days help.
Separation awareness
As babies grow more aware of separation, some protest sleep or wake seeking reassurance. Calm, consistent responses at bedtime usually carry this phase through.

Common questions
My baby’s sleep doesn’t match these numbers — is something wrong?
Usually not. These are averages, and healthy babies vary a lot from week to week and from one another. A baby who feeds, grows and is generally content is often simply on their own curve. Persistent worries are always worth a chat with your pediatrician.
How much should a baby sleep in 24 hours?
It changes with age and differs between babies. The figure above shows a typical range for this month, day and night combined — treat it as a guide, not a target.
These ranges are population averages, and the variation between healthy babies is wide and completely normal. A monthly guide can calibrate expectations, but it can’t resolve sleep — and no number here should make you anxious. Watch your baby, not only the clock.
