Have you tried transitioning to 2 naps? My little one is same age and does the below: Wakes @ 7am 1st nap @ 9am (usually 30 mins) 2nd nap @ 1pm (usually 1 hr 30 mins) Bedtime 7pm I read that once you struggle to fit the 3rd nap in, it may be time to transition to less naps
We’re on 2 naps now at 9months. Maybe slightly adjust wake windows. Wake @7am 1st nap @ 10.15am for 1 1/2 hours 2nd nap @ 3:15pm for 30 mins Bedtime 7:45pm
Limit it to 4-430. Playtime for a couple hours Andthen bedtime at 730. Usually works for my baby
