Re: working out and bf
I have never had a problem with working out and milk supply--you should be fine, as long as you continue nursing frequently and eat a reasonable amount of calories.
My DS doesn't like to nurse when I'm really workout sweaty--he seems to object to the salty stinky boob. If I take a quick shower, he's perfectly happy to nurse.
