PLZ HELP! 5:30am wake ups

28 weeks old, sleep trained. Sleeps great but consistently wakes at 5:30am, used to sleep til at least 6:30. 2.5/2.5/2.5/3 schedule. Bedtime 7:15pm. Naps capped at 2 hrs.

We tried to extend wake windows to get to 2 naps and it was a disaster - he didn’t seem ready and was a fussy mess for 24 hrs. He starts daycare in 1 week too so I’m not sure what to do. Help!!

Thank you.
