Re: Bridesmaid while breastfeeding - am I stressing for nothing.
Didn't read the other responses, but giving you my experience (if it helps any):
I was in a girlfriend's wedding when my DS was 4 months old. The dresses were not BFing-friendly. I ended up BFing right before we left for the wedding, in the limo post-wedding pre-pictures, and at the reception hall. I basically had to go into a bathroom and undress - in the limo my friend and fellow bridesmaid held up a blanket in front of me (we were stopped by a train and there were guys in the limo). It was a PITA, but it was worth it to me to be there for her big day. Baby was with me the whole day as well, and one of her aunts held him during the actual ceremony and any crucial parts of the pictures, toasts, etc. where I needed to be alone.
