*EDITED* Baby weight

As

My little girl will be 1 month tomorrow but for some reason *according to our measurements* she is only 8.8lbs which I think is 8lbs 12oz. She was born at 7lbs 8oz and got down to 6lbs 6oz because of the fact that my breastmilk hadn’t come in and her low blood sugar.

Is this normal or should I be worried? On month check up is next Friday.

Picture with my nephew.
