So Gideon has a terrible spit up and apparently a weight gain problem. We had tried every formula but no luck. The Dr said colic and gave us an rx for wic for similac alimentum. Well, not only does his colic seem worse but so does his spit up and he has diarrhea. We have these lactose drops you put in regular formula to help nabies with colic and have tried that for 24 hours and usually he spits up after every bottle and no spit up! I'm so confused. We tried reg and lactose free formula and it seemed to do nothing but now its ok? Wth?!
