Schedule help for nearly 7-month old - ready for 2 naps? Undertired? Overtired?

Hi all, would love your thoughts and advice on our schedule.

Baby turns 7 months in two weeks. We're still on three naps, wake windows being 2.5/2.5/2.5/3, give or take a few minutes.

Nap length differs wildly but we cap at 2.5 hours, although she usually only takes about 2 hours of naps.

I don't necessarily have a DWT.

Bedtime has been a struggle the past few days (and before that it wasn't great either 😂). Baby resists bedtime with all her might, but then is out cold when I feed her. However, she doesn't really settle into deep sleep until 1-2 hours after bedtime, leading me to believe she's overtired. She also sometimes wakes up crying from her naps.

Any advice?? Should I try 2 naps and do 3/3/4?
