Up and DOwn Up and Down!

Andrew LOVES stairs! He wants to go up them then back down over and over again. The problem is that he doesn't know how to get down them on his own yet so I have to be right there or he will just step out into the air. He isn't picky about his stairs either, the little set of three upstairs, the big tall set, outside front porch steps, other peoples steps- Danger calls wherever he is!!
