Try backing down with how much you give him to eat now and see if that helps.. I was SO hoping he was on the road to recovery. It is such a puzzeler as to what is causing this. Mine throw up every now and then but not enough to worry about but I know I would be worried to death if they were doing what Brodie is doing. We want our babies HEALTHY and happy... Poor little fella, can NOT be happy about throwing up so much.
