I'm curious since my 3 week old LO has only gained an average of .7 oz per day in the past 14 days (same scale & conditions). His dirty diaper output is also lower than I'm comfortable with. So I'm trying to problem solve... I didn't think his latch was a problem because it's not painful and it looks fairly deep...I also see him swallowing...but now I'm starting to second guess. I'm going to try to meet with an ibclc (there wasn't one on staff @ my hospital). Also ordering a brand new pump today.
