What's So Frightening About This Photo?

Well, not much I suppose. Until you are told that this was taken immediately after Jack got into his highchair.

By himself.

That's right. Everything was quiet (much too quiet). I stopped loading the dishwasher and peeked into the dining room. There was Jack--and if I may mix my similes for effect--grinning at me like he had swallowed a million bucks. He was sooooooooo pleased with himself. He had climbed up the foot rest, crawled over the black tray, turned around and sat himself down in the seat.

I'm going to have to think a bit about how to babyproof this one...
