Lazy nurser/weight gain issues/weird poop!

Ugh, been to the doc 3x this week with LO. She has been having watery poop that turned green a few times and with mucus. And she falls asleep at the breast constantly, not eating nearly enough. I was instructed to pump and feed 2 oz every 2 hrs and did this and it helped but it's driving me crazy to do all that work. I want to nurse and I want her to be good at it but it's not looking good. Any tips??? I have a call into a LC as of now, waiting for them to call back. I am just so frustrated. She is JUST back at her birth weight and she was born 22 days ago
