I have an 18 month old who was ebf for the first six months. After that we tailed it off a bit until we finally stopped at 14 months. He could feed for hours! Now it's the occasional night feed. Since the feeding has stopped more or less I've noticed my boobs are saggy. I'm a 32D so not flat chested but my nipples are lower than before and I have some stretch marks. Is it breastfeeding or just pregnancy that's done this?
