Another reflux baby here. Our boy also had a cow's milk intolerence, which I understand is pretty common amongst reflux babies, and a combination of ranitidine and cutting out cow's milk worked wonders for us. As I was breastfeeding this meant cutting cow's milk out of my diet. If you are formula feeding and suspect a cow's milk intolerence, you can get cow's milk free formula on prescription (it's the proteins in the milk that cause problems not the lactose, so lactose free formula won't cut it). Although it's not that long ago I can't for the life of me remember how long it took to notice a difference but I think it was within a few days and he was a completely different baby. Like Belle, we also used a sling a lot as he absolutely hated being put down. Reflux is just horrible, I do hope things get better soon. In the meantime feel free to PM me if you want.
