My baby girl was 6 wks early and formula feed from the begining b/c my milk didnt start to come in until 5 days. I still only get 2 oz a day from pumping and then feed her that. Is this doing her any good at all? She wont latch on for long enough b/c she tires out easily. It takes up so much time to pump 30 mins every 3 hrs to only get so little so I am trying to decide to keep doing it or not.
