I am 36 weeks pregnant and starting to think about nursing bras. I have one that I bought several weeks ago when I needed to go up a size (so I figure I might as well buy a nursing bra!). My rib cage has gotten WAY bigger throughout pregnancy, so even that one is getting a bit tight on the loosest setting. I also bought a soft, stretchy sports-bra type one that I figure will work through some size fluctuation.

Did you wait to buy your nursing bras after the baby is born? I have heard some people say that your boobs can get a lot bigger once your milk comes in. Or did you find that your end of pregnancy rib cage size/boob size was pretty consistent with what you had while nursing? Or does the rib cage shrink after pregnancy, even while nursing?

So many questions - this all seems so foreign! I don't really want to be running out to buy nursing bras with a brand new baby, but I don't want to shell out $$ for them now if they might not fit after he is born.
