We were playing out in the yard today when you came running to me, going "Owie! Owie!" and rubbing your hand against your chest. I saw a sting mark on the top of your right hand, and I figured that you'd been stung by a wasp.
We immediately went into the house, washed your hand off with soap and water, and put some triple antibiotic and hydrocort cream on it. You were very brave and didn't cry or whine, but I gave you some acetominophen and some benadryl just in case, as your hand was swelling up.
Thankfully, after some initial crankiness and after a nap, you were all better and the swelling had gone almost all the way down. I watched you for any other symptoms while you napped, but you slept peacefully.
