Fell out of a high chair!

We went to a family get-together this evening, which was held in a local church fellowship hall. As everyone was eating and socializing, one of our little 18 month old cousins leaned forward in a high chair, and the tray came off. He fell forward, smacked his head on the table, and then hit the floor. It wasn't even my kid, but I thought I was going to throw up it upset me so badly. Lately I have been a bit lazy about strapping DS in to his high chair at home, but this definitely scared me straight. It also made me suddenly become a lot more particular about what kind of high chair I will let DS sit in when we are not at home. Thankfully the little guy is okay and came away with just a bruise.
