does anyone have any experience of this in infants. I have been told to give my 17 month old daughter a milk free diet for 6 weeks to see if she has an allergy. She has a long history of being unwell with chest infections, colds and poor weight gain so they are now trying to connect this with a possible allergy. They are not thinking lactose intolerance but cows milk allergy due to her symptoms. I am none the wiser on either..can anyone help?
