Walking?

Brody is taking more and more steps every day. He is getting so brave about walking. At first he seemed very timid and a little nervous about it. Now, he is just "walking" all day from activity table to the couch, the couch to the rocking horse, and on and on. He is still crawling a bunch but he is getting the hang of it and seems to be enjoying it. He will start to giggle when he takes his steps. It's really cute. I just don't know when to say he is officially walking...
