My dd is 15 months old and has an egg allergy. It is fine when dealing with close family and friends as I have explained it to them and just remind them to check ingredients if they are giving her anything. The other day a friend of my dad asked me if she could have a bar of chocolate. Before I could say anything my mother said 'no, she has allergies' and the poor man looked taken aback. I want to be able to tell people in a polite but firm way without sounding like an over anxious mother. I think some older people think allergies are all in the mind but dd has been properly diagnosed after a bad reaction so we can't take any chances.
