3 month old sleep schedule: Bedtime and nap schedule
At 3 months, your baby's sleep may settle into a recognizable flow. Sleep architecture is also maturing at this age, which can mean more noticeable wake-ups as sleep cycles organize. Most babies will sleep about 14 - 17 hours across 24 hours, with at least 10 hours at night and 4 - 5 daytime naps. Wake windows tend to run 60 - 120 minutes.

3-month milestones to watch for
Every baby develops on their own timeline, but here are the milestones most 3 month olds hit. Use it as a gentle guide, not a checklist to stress over.
🤸
Motor
- ✓Lifts head at 45 degrees and pushes chest off the floor during tummy time
- ✓Briefly grasps toys placed in hand and looks at them
- ✓Brings hands to mouth
- ✓May show early signs of rolling, like reaching for toys while on tummy
🗣️
Communication
- ✓Cooing and babbling sounds begin
- ✓Cries with distinct sounds for different needs
- ✓Witching-hour fussiness typically resolves by 12 weeks
👀
Cognitive
- ✓Tracks moving objects with eyes
- ✓Turns head toward sounds
- ✓Recognizes familiar people at a distance
- ✓Color vision is coming online, sees brights more than pastels
💛
Social & Emotional
- ✓Social smiles, especially at familiar voices
- ✓Makes intentional eye contact
- ✓Watches faces and expressions closely
- ✓Smiles back when you smile
Heads up: If many of these milestones haven't shown up, your baby seems to have lost a skill they had, or something feels off, reach out to your healthcare provider. Trust your instincts — you know your baby best.
