It is the time of the year for bees to begin "hunting". Bees sting as a defense measure and the pain and swelling from bee stings can be a cause for concern.
Avoid things that attract bees. Avoid fragrances and other sweet smells. Don't wear bright colors or look like a flower patch. Be careful with food and open cans of soda. If a bee lands on your child, tell them to act like a "statue". Hasty movements will triger the aggression in a bee.
For more information on treatment and when to call your doctor see Dr. Greene's article. If you know your child is "allergic" to bees talk to your doctor. If there is difficulty breathing, call 911 immediately.
