My 12 years old son is allergic to peanuts and I could realize it lately when he grew sick whenever he ate peanuts, even in a dessert. I want to know if it is just he who has this type of allergy or are there other kids as well who are allergic to peanuts? In addition, I would like to know about food allergies, as no one in my family has been allergic to something like peanuts. I am really bothered about his health, although, he is not allergic to any other food! I would really like to know if I need to take any precautions to avoid it. Please somebody advise appropriately. Thanks.
