Hello, I am new to LLL and a new mother of a 5 week old, Andrew. I am mainly breast feeding with a little bit of formula supplement. Very frequently when it is time to breastfeed my baby I get this feeling in both my nipples like they are tightening up just at the very tips of the nipples. It usually lasts for only a few seconds but I have never heard anyone else speak of this feeling, and I don't think it has to do with engorgement. But I am curious as to what this occourence is and if it has a name and what it's all about. Does anyone know? Thank you.
