I only had my daughter 4 days ago and I can't get anything from my breasts. Her pediatrician after only being 2 days old suggested we supplement with formula. I gave my baby the bottle and pumped to stimulate. Now I'm engorged and still nothing when I pump!! My breasts are so hard and lumpy and feel tight. I'm so lost and I don't want to give up trying to breast feed. Any insight or suggestions?
