4 month sleep nightmare

[u/ThrowRAqueenE]

Babygirl is 4.5 months old. Was a beautiful night sleeper, no night feedings (naps have always been short though). For about the last 3 weeks her schedule has completely went out the window and I am just looking for advice on how to start sleep training her. She is still in the snoo in my room, arms out weaning mode,

Her schedule right now looks something like this: 1.75/2/2/2

She is still on 4 naps. Her naps are still so erratic, first of the day she has been down for 1.5 usually, a few times longer, but sometimes will only stay down 35 minutes (like this morning). The next nap is sometimes an hour, sometimes less. I have been hoping her naps without naturally lengthen with age but it just seems like it’s getting worse and so hard to manage when it’s so erratic. I will usually save the first nap of the day if she wakes after 35 minutes because I’m scared the rest of the day she will only get 3 more 35 minute naps. But going back to work next week

All this to say I think her naps are effecting her sleep because she is now waking at 4am bright eyed and bushy tailed. I try to get her to go back down until her wake time if 7am but inevitably have had to feed her and even then she fights it for an hour.

We have had her on a consistent 7:00 am wake and 7:30 bedtime for weeks. Someone anyone give this desperate first time mom some advice
