M.P.
The exact same thing happened to me as a kid and now happens to my daughter. It is really unfortunate and uncomfortable. I don't have good answers, a benedryl pill seems to help my daughter and I only give it as needed. As the summer progresses, her reactions do decrease. We also use a chilled lavender seed filled pillow to reduce the swelling as well. We are also firm believers in bug spray as yucky as it is. You definitely have my sympathy. It's just a very unfortunate thing. I'll be looking forward to other people's suggestions, too!
