That is not mean at all

Thankfully I don't have a child with any allergies

I am the one with all of the allergies, fortunately I did not pass on the allergy genes and my DS appears to have inherited my DH's no allergy genes
I do however understand how your children feel as I have had anaphylactic PA and many Tree nut allergies my whole life. So I have had almost 40 years of having to miss out on many delicious looking things that others eat around me and it's a great feeling sometimes when you get a "special dessert" and you see others looking and you can see they want what you have

. Funny thing is it doesn't bother me that much when I see a dessert buffet with treats with nuts, as the reaction is so bad and it really is a terrible feeling having an anaphylactic reaction, so it makes me really have no desire to eat it, but I LOVE getting a special plate. I guess it's like anybody who really really does not like a food, you don't feel like you are missing out when you don't like it in the first place. I have had somebody ask before how do I know that I don't like nuts if I haven't eaten them, well it's the reaction that I get feels so horrible that thinking about a PN makes me shudder, yuk, so I don't feel bad not eating it. I guess maybe as a child it bothered me, but to be honest I can't really remember that. So all of your children will grow up not knowing any different, they will never have had a PN or TN (or dairy or whatever their allergy is) and their reaction really is not a pleasant feeling, so when they avoid it, it is just normal, because that is all they have known if that makes sense. It would be harder to develop this as an adult as you have eaten something your whole life and then have to suddenly not eat it. Children with allergies grow up never having eaten their allergen so really don't know any different. My DS can be sitting there munching on some chocolate covered macadamia nuts and I have absolutely no desire to eat them, to me they are eewwwee yuk, yet I love chocolate, but the thought of a nut gives me the shivers so I have no desire to eat it and don't feel like I'm missing out, I get more excited about a banana than a cupcake that has some sort of peanut/nut ingredient

. On saying that as I do love chocolate, when I do see yummy desserts that are safe, I get very excited
