Well, update...........we tried goats milk, she did ok with small amounts but after we had increased it gradually she had the same reaction that she had to the cows milk,
we have seen a paediatrician, he listened to our description of what happened with her, told us to go back to using formula for 6 - 12 months and that it was nutritionally fine for her, he also referred us to a nutritionist for us to get extra advice on diet and vitamins etc...........
Its a pain, but thats life,
