my ds2 9mths old has cows milk allergy, bad reflux, has not taken well to solids (can only manage the very bland baby rice) well, the list just goes on and on. anyway, he is going to have a ph study at gosh and the nurse who called us to arrange it said they would also like to run a 'milk allergy protocol' at the same time. Anyone experienced this? I googled it and internet suggests babies are exposed to tiny bits of cow's milk to de-sentitise them. Is this right?
