Boy versus Bee...
...and the winner was: the bee!
We were all outside, but neither Matt nor I saw exactly what happened. Matt responded to the screams first and found a red mark on the middle of Levi's upper lip. Levi told us "yes" when asked if a bee stung him. Later on, I asked him if the bee just flew up to him or if he was trying to touch the bee, he told me that he was "touchin' the bees" - so the details of the sting are still a bit fuzzy :)
The poor kid had quite the swollen lip until bedtime on Saturday night, but other than the swelling, he had no ill effects from the sting. I've since been told a few home remedies to try for reducing the swelling - good thing, since I think this won't be the only sting for our curious boy!
