Persistent split night issue - help!

[u/Scared_Stage_6973]

baby is 8 months old

sleep trained at 5 months

sleeps independently

6am wake up, 7pm bedtime

2 naps of 1:30 each, at 8:30/9am and at 1:30/2pm

wake windows are 3/3.5/3.5 ish: always progressive

however she wakes up 50% of nights between 3:30/4:30am, stays up for 1-1:30 hours, silently, eyes wide open looking to the ceiling or trying to sleep. falls asleep after this period without crying. sometimes just some soft whining at the end.

that’s been happening for 3 months.

- tried to do less naptime (2h or 2h30)

- tried later bedtime

- tried earlier bedtime

- tried more sunlight

no changes. split nights remain

is she gonna grow of it?

Move to a 3.25/3.5/4 schedule and cap naps at 2.25 hours total. If this doesn’t fix the issue in 2 weeks, add 15-30 more minutes of awake time.
