4 → 3 Naps
4–5 months- Can stay awake 2+ hours without melting down
- The 4th nap is tiny (under 15 min) or not happening
- The late catnap is pushing bedtime past 8 PM
- Baby seems content and alert during longer wake windows
- Drop the late-afternoon catnap first
- Stretch wake windows by 10–15 minutes every few days
- Move bedtime 30 minutes earlier temporarily to prevent overtiredness
- Allow 1–2 weeks for the transition to settle
