How to think about 3 months sleep
The 75 to 110 min awake range is a reference, not a rule. Your baby’s cues still matter most: yawning, staring away, fussiness, arching, or losing interest may show up earlier than expected.
Instead of building a rigid clock schedule, repeat small cues: daylight in the morning, darker nights, calm changes, and a short sequence before sleep.

Sleep cues to watch
Routine gets easier when you act on early cues before your baby becomes overtired.
- Staring away or turning the face from stimulation.
- Yawning, hiccups, or slower movement.
- Fussiness that does not improve with play.
- Seeking cuddles, feeding, or sucking to regulate.
What to track in Blumy
Tracking should reduce mental load. At this stage, sleep, feeds, and diapers are usually enough to show the most useful pattern.
- When your baby fell asleep and woke up.
- Feeds or bottles around naps.
- Wet and dirty diapers.
- Notes to discuss with your pediatrician if something worries you.
