I'm usually on the Sept 11 board, but I'm nearly eight months, and it seems like, after their 1st tri growth spurt, the girls haven't changed much for the rest of this pregnancy. My question is, when do you ladies think is the best time to buy nursing bras? How many band/cup sizes did you go up after your milk came in? I'd like to start getting a couple nursing bras soon, but I don't want to make either mistake of buying them too large in advance, or buying them at my current size and then not being able to use them. What has been your experience?
