Two weeks ago I stopped BF my nearly 7mo DD, we were at that point down to 2/3 BF a day, before bed & in the night. Now my nursing bras are too big & pre-pregnancy 32B's too small, I'm back to pre-pregnancy weight & don't plan on loosing any more but I don't want to go out & buy all new bras to then a month or so later have to buy more as they've changed size again. How long roughly can I expect it to take to settle in a size?
