I have been b/f my 5-week old since birth and have been having much success. But I am curious about something. I have never experienced the FEELING of the let-down reflex in my breast. I understand that is the experience of many and that there is nothing to worry about if you don't feel it. I have, however, felt a tingling on my BACK when it lets down. I am wondering if anyone has ever experienced this or knows of anyone else that has. I am not really worried about anything, just curious, I guess. I get pins and needles kind of feeling in the middle of my back when she nurses. And it is not the position we are in, since I nurse in many positions (sitting on couch, lounge chair, lying down, etc.) and it happens in all positions. I just find it kind of odd . . . .
