Sam had a mild dairy intolerance - which means that the HA formula was ok, but regular ones were not. He can now drink lactose-free milk or long-life milk but not regular cows milk. Believe me, if we could have changed to a cheaper one, we would have! I hope the change goes well - and you'll know soon enough if it doesn't suit him - for us it was chunkier (and stinkier!) spews and feral nappies.
