When I was a teenager, I once accidentally dropped my little sister--then an infant--face-down onto a hard linoleum floor. She cried really hard for a few minutes, but was otherwise OK.

Her reflexes must have kept her from hitting her head too hard. I swear babies are made of rubber.

Yes, I have since told her about the incident. :-/

When I was six and my little sister was ~2, I was running her stroller down the driveway and stopped suddenly. She kept going. I got in trouble.
