Babies and their weight

Hailey
My daughter was 6lbs 15oz when born at her two month appointment she was exactly 10lbs her doctor made me feel like shit as if I wasn't feeding her enough . I feed her every 2.5 to 3hrs and all she wants to drink is up to 3.5 oz max . So now I'm stressed out feeling like I'm starving my daughter . What was your baby's weight progress at 2 month appointment ? Should I be worried ?
