question: Hi doctor, My baby girl is 45 days old. She is fully breastfed. At many times, she seems to be fussy and aggressive while I nurse her. I rule out either the possibility of milk being too fast or too slow since on both occasions she seems to react the same. After being fussy, she appears to be on and off from my nipple and screams when I pull her off from my breast and cries when offered milk. After crying for a few minutes, I swing her and she goes back to sleep. Her crying is so painful to watch. Can you help me with this?
