Feeling inadequate.

I don't know what I'm doing wrong with bf. She eats every 2-3 hours during the day. I know she's getting milk bc I can hear the swallowing. When we go to our support group she's gotten 1.4 oz the last time. She has plenty of wet diapers. Yesterday she did so well and now today it's like a fight. She still has wet diapers but she hasn't popped today. We just got back from the pediatrician and she hasn't gained any weight from leaving the hospital. ????
