I'm confused about nursing bra sizing. I know that you should get fitted around 38 weeks when the baby has 'dropped' and that you should get a bra that's big enough in the cups to cope with engorgement after day 3.
But what I don't know is how long it takes after the birth for your ribs to go back to your pre-preg size, and also how long after the birth it is that your boobs are huge. Do they stay huge until you wean? I don't want to spend loads of money on nursing bras that are only going to fit me for a month (nb. not planning on weaning at 1mth!).
