How might managing food allergies get harder as my child gets older?

When children with food allergies develop new, more independent social lives, it becomes harder and harder to manage their allergy. When they are with their peers at coffee shops and malls they will be tempted by easy access to ice cream and other possibly verboten foods. If their friends are ordering sundaes, who's to say that they may not put peanuts on them, even if they risk accidental exposure? They don't want to be the one kid at the confirmation parties or Bar Mitzvahs who never gets to eat and always has to watch out for what others have eaten. These feelings of strangeness can cause a lonely period of life to be even lonelier, although there are always those who feel special -- usually girls -- because they get to carry medicine with them.
