Baby wants to eat a lot

Or is this normal?

She ate 2oz at 6:30 now it’s 8:00 and she was crying for her bottle so I gave her another but I’m a stop at 1oz or should I just let her do the 2oz

Is this ok.

She can go 3-4 hours asleep not eating and then she’ll do this...

During the day it’s ok but night time 😳

I know the pediatrician said she’ll let me know when she’s hungry.. so what do u guys think?

Just looking for advice
