Baby born April 15th and still wakes up every night at 1 am

Michelle

I keep reading babies this age sleep from 8-5 or close to it but my baby still wakes up 3 times a night. Is this just me?? (I feed her a bottle at 7:30 pm every night). I let her cry at 1 am and she doesn’t stop so I end up feeding her and it’s not getting any better. Help!
