peek-a-boo?

Henry is quite proud of his new found peek-a-boo skills.....so proud that he thinks the skill transfers to all his toys. He takes plastic keys, blocks, diaper rash cream, or whatever he is chewing on at that moment and holds it high up over his head with his arms straight. Then, he quickly brings his arms, and the toy, down to chest level. He now thinks this is how you play peek-a-boo; the whole 'hiding' facet is lost on him.

But why wouldn't he think this is peek-a-boo? Every time he does it, Taylor and I yell "peek-a-boo" like he just invented the game. It's pretty funny. Or at least it's pretty funny when you are the mama. or the daddy.
