My daughter is 3 weeks old. Nursing was going ok, she would latch and eat but it was pretty painful, the first week. At our 1 week appointment she was gaining weight and doing well so we decided to introduce a pacifier to help get more sleep at night. At her next appointment she had lost weight and did not gain for a whole week so the pediatrician had us supplement with formula. After 1 bottle she no longer wanted to nurse. So now I am pumping and alternating breast milk and formula at feedings. My supply with pumping is not very good, often less than half an ounce from 20 min double pumping. I would really like to try to get her back to nursing regularly but am afraid to stop supplementing because of the weight loss before. I would like any advise.
