Oh, he's a monkey alright

You know that song, "10 Little Monkeys?"  I've got one.  Tonight, he is leaning over the rail of his bed, standing up (probably jumping) and goes right over the top of it.  Ends up with a bloody nose, a fat lip and a grumpy mom because I was nursing the baby at the time and he was supposed to be in bed going to sleep.  God must have made three year olds cute so that they would live to be four.
