My baby is 9 and a half months old. Her schedule has been really good, 2 naps per day, 3-3.5 hrs wake windows. Would wake up on her own anywhere between 6:58-7:10 every morning. She’s been waking up at 6 am for the last four nights. We’ve been trying to tweak the schedule, earlier bedtime, later bedtime and nothings changed. Her naps total anywhere between 2.5-3 hours total a day. She has a bedtime routine and has been sleep trained.

Any idea on what is going on and how to stop these 6am wakes?
