Problem: Ouch! Running around barefoot on the boardwalk is fun, until there's a tiny piece of wood ingrained in your kid's hand or foot.
Solved: To prevent infection, the most important thing you can do is keep the splinter site clean. Wash it with soap and water, then use a pair of sterilized tweezers to pry the wood out. Alternatively, if it's sticking out of the skin's surface, you can try putting a piece of Scotch tape on to see if it'll come out that way instead.
