My daughter will be 3 weeks old on Thursday and she's been on 2oz of formula every 2-3 hours. She's been wanting it every 2 hours on the dot so I upped it to 3oz. She STILL wants to eat every 2 hours and I don't know how to get her stop and wait because she will scream and shove her fists in her mouth until she gets it. I'm going crazy, and don't know what else I could do!
