Green, just quickly... sounds like it's a cows milk protein intolerance rather than a lactose issue.

Friend's bub had the same issue - for one child goats milk formula was ok, but the next was intolerant to the proteins in that one as well and he had to go onto neocate - an elemental formula only available on prescription. If you're worried about soy (and I would be, but that's me!) then neocate could be the best option.

Must dash!
