Right now me and the wife are sharing a house with another family who has three kids. Two nights ago their two year old got into an accident. Me and my wife heard a thud at around 4 am, and then we heard the youngest crying loudly. We correctly assumed that he must have fallen off the bed and hurt himself. We heard the parents rushing about, but after a few minutes the crying stopped so we assumed it wasn't serious. Then we heard the mother talking to her husband and she was clearly crying. The mother came to our bedroom door and called my wife. My wife opened the door and I heard the woman say that the kid had cracked his head. Then I heard her sobbing (kind of a hiccuping sound) for a few seconds. When I came out of the room she had stopped crying, but there were tears in her eyes. She told us to watch the other kids while they took the two year old to the hospital.

The kid was ok though. Turns out he rolled out of the bed and hit his head on a block of lego which gave him a nasty cut instead of a cracked skull.
