What to know at 4 month old
The 4-month sleep regression is common as sleep cycles mature — it passes. Watch your baby’s tired cues — yawning, looking away, fussing — rather than the clock alone, and keep the room dark and cool for sleep.
Tips for better sleep
- Aim for a wake window of about 90-120 min to avoid an overtired baby.
- Keep a short, consistent wind-down routine before each sleep.
- A dark room and white noise can help lengthen naps.
- Put baby down drowsy but awake when you can, to build self-settling.
