So DD has a suspected cows milk allergy. This has yet to be confirmed. HV has suggested giving her some cows milk and 'seeing what happens'. I am reluctant to do this as she had two spoonfuls of milk containing porridge previously and was covered instantly in hives. I'm concerned that next time might be even worse. Would you try it? Is this quite normal? I'm awaiting a referral to a dietician if that makes any difference
