Spring in January ?

How does this thing work???

It was a nice spring day in January. So, Marc and I blew up Matt's bounce house. Yes, it was only one of his many, many gifts this Christmas. He had a great time playing in it even if he can't figure out how to jump around yet! He spent over an hour just rolling around inside and throwing the little plastic balls that came with it. It is supposed to be warm again tomorrow so maybe we will get it out again for him to use before the cold weather comes back.
