My 3 year old stuck a decent chunk of blue playdoh up his nostril once. He came to me crying with blue snot streaming out of his nose. Took about an hour to get it out - working his nose every five minutes and then letting the natural juices work the playdoh to where it would run out.
My third son, now three years old, has TWICE pulled the hold up stick out of the window and gotten his head slammed and pinned. He also has lost three of his top front teeth in a toy car accident.
My second oldest son smashed his toe in a window, not once but twice. Same window, same accident. I guess he forgot.
My oldest son once fell out of a tree, miraculously not killing himself. Seems they were playing "tree dodge ball" with a football. If he hadn't hit the large branch on the way down, which bruised his ribs and flipped him over, he may have hit hard enough to be killed or paralyzed.
Me? I set a couch on fire with matches when I was very young.
