Thanks for the replies everyone.

Rufalina: This has been going on for over a month now and is getting progressively worse so im not sure that it will sort itself out in its own. We have gone back to formula today so see what happens.

Astrolady: That is ridiculous re: your doc. Im not sure that it is lactose intolerance as he has never had a prob with formula but guess it wouldn't hurt to check it out.

Junglemum: Thats interesting about the protein in milk. DH did mention trying A2 milk see if that makes a difference. Think i will just go see the gp and see what he says. Prob worth checking out.
