I only took extra vitamins (c, zinc, probiotic, colostrom...)for the infection. His poop is great. Mustardy, seedy, and several times a day. He gets 2 oz every 2-3 hours from the supplementer. Maybe it's just my pump? I'm only using the Ameda purely yours. I've never felt engorged, but do feel a small difference after he eats in the way my breasts feel. Hopefully he's getting more than I think.
