If you're traveling or eating with family for the holidays, take the EpiPen trainer with you. You probably know how to use it, but teach your friends and family too. First, they may need to know how to administer the EpiPen one day. Second, if you explain the response (preloaded needle + 911) to eating an unsafe cookie, maybe they'll help prevent contact with unsafe cookies (or unsafe foods in general).
If you don't know how to use your EpiPen, there's a GREAT resource here: http://www.epipen.com/how-to-use-epipenIf you have expired EpiPens ~ take those too and let family give an Epi shot into an orange or grapefruit. Whoa! It's different from the trainer, because obviously there's a needle. PLEASE be careful (of course!). If you're not interested in triggering your expired EpiPen, but want to see what the needle looks like, you can watch this "Food Allergy" episode clip from a Dr. Oz show, here.
