My daughter is 7 weeks old and has been a good eater from the start on both breasts. She gained weight well and is taking some antacids because of mild reflux. Just two days ago she started to only nurse one side. If I put her on the other side she thrashes about and won't take it.

I'm concerned that she isn't eating enough but she does have consistent wet and poopy diapers. I'm also full on the side she doesn't eat on, but should I pump or will this slow my supply down?

Thanks for the help!
