Good question.As NAN3 is indeed a cow' milk based formula it is odd that your little girl cannot tolerate full cream cow's milk. She is unlikely to be allergic to milk and also unlikely to have a lactose intolerance as she is symptom free on the NAN3. In spite of what I have just said here, your little girl's symptoms when she drinks cows milk do suggest that she may have a problem with lactose intolerance.Try her on a regular soya milk in cartons which you will find in most supermarkets. Let me know if she is unable to tolerate this type of milk.
