Yesterday, I received a call from another mom that I had recently met on the playground. Our pre-school-aged kids found each other through a pick-up game of baseball over the Summer and had been playing together almost every day. According to the mom, yesterday's game was no different than previous ones. My son's yellow wiffle ball bat was used by all of the kids as they took their turns at bat, and the mothers and caretakers took turns serving as pitchers. As the game wound down, an older child picked up the bat and whacked her son on the forehead (I'm still not sure if it was an accident or on purpose), resulting in gushing blood and ultimately five stitches to the head. She obviously was very upset (as we all would be if we had just taken our child to the hospital), but she also insinuated that I was to blame for this because it was our bat that was used and that my son's nanny should have been "paying more attention so this wouldn't have happened."
I checked our bat, it was fine. No cuts in the plastic, no jagged edges, etc. I spoke to my son and his nanny and learned that he was "in the outfield" when the incident occurred and by the time they realized what had happened, the boy's mother had already scooped him up and run out of the park. Am I at fault here?
