Feeding baby

So, my daughter is a week old today and gaining weight like she's supposed to. Her pediatrician is trying to force me to formula feed saying she isn't getting enough from me. I tried breast feeding but I drown her so I started pumping and I pump 6 oz of milk in 30 mins. She eats 2, sometimes 2 1/2 oz every 3-ish hours. Should I just switch pediatricians?

Also, they're trying to make me wake her to feed her every 2 hours, when she wakes up every 3, or 3 1/2 on her own bc shes hungry. I know there are a bunch of different opinions out there but I'm just curious to see what other mommas think. I'm a FTM but I have been basically raising my cousin's baby since he was a week old
