Hey, full-figure moms!
I haven't ordered any yet, but someone on another board just posted this link, and I was like "Hallelujah, a nursing bra for my giant boobies!" I thought I'd share:

They are a little pricey, but I had a really hard time finding any nursing bras when I started and appreciated any leads I could get.
P.S. Before I get a bunch of flames about being a troll or something, I'm a real person who is just trying to be helpful. If you don't like it, don't click it.
