Thanks ladies for all your comments, you are a great help x
Yes the GP did also say it would only be temporary, hence why he suggested a 6 week change in diet, but when we reintroduced 'milk' again it didn't go to plan. He still thinks it is temporary and thats why we are doing the test again at 12months.
Maybe his problem is with the Lactose then, i feel terrible for not knowing for sure!
