I've been musing on this today. In the hospital when bfing was painful my was unconsciously tensing my shoulders when I was latching DD on. The midwives told me to relax otherwise my milk wouldn't let down. I believed them at the time, but following a lot of reading about bfing it doesn't seem right to me. From what I have read only extreme stress can restrict letdown and only temporarily. Am I right and were they talking shite? Wouldn't be a surprise, tbh.
