Crawling up the stairs

Isaiah loves to crawl up our stairs. crawling up all 12 takes quit a bit of time though. We have 2 stairs going down into the living room, and 2 stairs going up to our room, he loves to crawl up those all day long. The sad part is once he is up there, he can't crawl down them, so he sits and cries until I get him. It is pretty cute! Sooner than later though, he will be doing both.
