In addition to reading a copy of "The BugaBees" (my suggestion) FAAN has a great list of ideas to help get you started. Among other things, FAAN's web site offers free downloadable presentations, talking points, coloring pages and more. Beyond that, this video from Nick News is still one of my favorites to share with kids and adults.
If you're not the group-presentation-giving type, consider other ways you can help build awareness. Refresh friends and family members on Epi-pen protocols. Send a special "thank you" card to those most supportive to you and/or your children's food allergies. And if you're someone who doesn't have to deal with food allergies on a regular basis, take time to educate yourself --- you just might save a life one day!
