I breastfed all 3 of my kids for 6 months. With 2 of them, I had no engorgement issues. With 1 I had a tiny bit of leaking (mostly nipples that were a little (soft)crusty for a few days. But my 3rd child where my supply was considerably less, I experienced absolutely nothing (except my bra size has gone down from a B to an A - but that happened after my 1st baby). I call them the deflated balloons.
Good luck!
