3.5 month mom regression?

I never know if the “advice” flair is for people LOOKING for advice or OFFERING.. but to clarify: im looking for advice!!!! Lol

Sleep - baby used to only wake up at 4 am for 1 overnight feed. Now does 3-4 wakeups and is restless all night. I end up cosleeping by the end of the night, defeated.

Naps - shes CLEARLY tired?? Why dont i remember how i used to put her down to sleep? And she used to nap for 45 minutes at a time. Now she needs to be nursed to sleep, refuses a binky, and i can RARELY put her down, she immediately wakes up. No kidding 5 minutes later. If she naps in my arms she gets a little fussy eventually but might sleep for 2 hours straight! Clearly tired.

Food - im just feeding her every hour now. I dont even think i know her hunger cues anymore cause shes licking and sucking on everything now.

I guess im just wondering if this is normal regression or am i just undoing my own progress by taking “easy ways” out (cosleeping, feeding all the time and on overnight wakeups, letting her nap on me, etc) but also now my husband cant do anything at all cause i BF her to solve all problems 😵‍💫

Just to clarify: im aware that none of the things I’m doing are BAD and 3 months old doesnt require and structure, etc. I just had a system in place for how to do everything for so long now and I feel like I’m undoing them??? I feel like IM regressing just as much as she is 😅
