Nap schedules?

My babe is around 7.5 months and some days her naps are F’d up bc she wakes at like 5-530am! And sometimes she has a 2 hour nap in the AM and sometimes she takes 30-40 mins 😒 she’s at 3 naps a day and can hardly stay awake for 2 hours before her first nap. So if she wakes around 6am (which is good and okay), first nap is 8, second is around 1130/12 and last naps at 330ish. Bedtime is anywhere from 6-7pm depending on her naps. I usually do 2/2.25/3/2.5 for wake windows roughly
