Hi Ive been breast feeding my ds for the 1st six months( due to my milk allergy) and have started weaning. Yesterday i tried him with a jar of hipp organics lamb and vegetables (to see if he likes it before making my own) he had a reaction to it and was covered from head to toe in a rash. The Hv suggested me trying cooking with butter as ds not gaining much weight so cooked some beef in butter the following day bigger more prominent rash. When checking lamb jar it had whole milk in it ( even though it was from 4 months) Does this sound like an allergy to milk???? hes never done this with anything else. If so whats the next step???
