I need sleep!!!!!

Helppppppo my 5 month old will sleep from 9 pm - 3 am beautifully (with the exception of a couple of times) but begin waking up after 3 am every hour of the damn night 🥴

I quickly pick her up from her crib and try to rock her to sleep but the second I go lie her down she wakes up and if she does go down successfully you better believe she’s up again in 30-60 minutes. I try to feed her (breastfeed) every time she wakes thinking she’s hungry but she still always wakes up no matter how much I feed her. I’ve tried cosleeping but she just fidgets like she’s uncomfortable. During the day she naps every two hours but can range from 10-40 minutes max.

You can only imagine how frustrating this is for me every night. I have a meltdown I just want to sleep:( can someone tell me what I’m doing wrong
