Leanne has a great tip for helping kids deal with the inevitable summer bug bites:
Toddlers and preschoolers have little self-control when it comes to not scratching mosquito bites. When my 2 year-old got a bad sting recently and almost infected it with his scratching, I hacked up a little device that worked like a charm:
After putting some Benedryl cream on his bite to reduce the itching and swelling, I cut the foot out of an old sock and put the sock over his ankle like a leg warmer. This simple barrier kept him from scratching and kept the sore out of sight and out of mind. I bet this would work well for arms and upper legs or calves, too.
As for bug bites, another Parenthacker had good luck with insect-repelling bracelets.
