The first time that baby choked while breastfeeding, I thought I had drowned my baby. Her little cough was so sad. I immediately sat her up and started patting her back. She seemed to get over it quickly and wanted to go back to feeding. I asked our pediatrician about how to prevent the choking. He said that she probably choked during a milk let down. At the time, I didn't know when my let down was occuring. Now I can tell. I feel a tingling near the tip of my nipple when I let down. The doctor said that I could press my finger just above baby's latch to slow down the milk. Seemed to help. Now she delatches by herself during a let down. The first time she did, the milk sprayed all over her face. :)
