Hi Valerie,
Good luck with your son. He will do fine by just being aware and careful. The best thing is to educate him and the people with most contact with him. Unfortunately many things can cause a reaction but just to know how you feel when exposed can help you from staying away from what is bothering you. Many supplies today will tell you if it is latex free but not all. For me, anything that stretches, stay away from. Synthetics are good, such as lycra spandex: but not spandex alone. Erasers are rubber in school, carpets, etc.. Avoid at all costs balloon birthday parties. There is so much info to know and it is out there to learn. If you want to discuss anything, feel free to write me.
