Re: One let down per feeding - normal?
I have only ever felt one letdown, and I had a very intense letdown sensation). When I have pumped I have gotten multiple letdowns, but I only feel the first. I don't know what happen when my son nurses (I've only felt one letdown and I don't really feel that anymore, plus my son's sucking pattern never looked the way they tell you it should), but he has thrived on his milk.
As long as weight gain and diapers are good, then there is nothing to worry about.
