So we think the boy broke his leg/ankle when he was jumping on hotel beds in Berkeley. Yes, we allow our kids to go crazy on hotel beds. I think I was in a meeting when it happened (edit/they weren't alone in the hotel room; their father was present), and everyone's a little fuzzy on the details anyway. But there seems to be a vague memory of the boy saying, "Owww!" after one of the jumps. There was a little swelling later, but it went down quickly, so we thought he just twisted it a little. The swelling (which was just a tiny circle of fluid on the little bone that sticks out from the ankle) came back about a month or two later. Then went away. Then came back. Then went away. Then came back and stuck around. Then, we went to the doctor. She said it was a cyst and sent us to get x-rays to determine whether or not it watch attached to any ligaments or anything.
Not a cyst!
The biggest moment was when the boy found out that he needed a cast and that he wasn't going to be able to swim*. He was crying in the doctor's office. The girl was watching him so somberly, clearly tuned into his grief. Then he said, "I don't want [the girl] to swim if I can't because I don't want to have to watch her" (he was referencing our upcoming hotel stays, which usually include swimming as well as bed jumping). The girl, who loves to swim, without pause and with a very serious and earnest face said quickly, "I don't like swimming."
It was so sweet.
*We have since learned that there are water sock things kids can wear that will allow them to swim with a cast.
