I'm still nursing dd#1 and haven't leaked any this time. I wonder if it's cause my nipples still remember that they're supposed to keep the milk in. I dunno, it's an interesting question though. Cause last time I just poured colostrum and milk until dd was over a year old, this time, not even a drop has leaked.
Oh and about the sweat thing, my pits always smell. <sigh> guess it could be worse. And my boobs are a 36 F, and have been at least a DD for five or more years, so I'm so used to the under boob sweat and cleavage spring. It's just one more reason why I wonder why women with little boobs want big ones. I want little perky boobs, not my national geographic boluses.
