Sarah - his first lot of formula was karicare gold, then, he went to karicare gold plus - and thats when the reflux got diagonised, and i sometimes wonder if it was related. now he is on novalac for reflux, but, want to try him on something else, and something more easily available. But, its hard to change formulas, as, i hate the idea of buying something, only to discover its no good, and then its such a waste of money. but, what choice do we have?
