The pitter patter of little feet

I was sitting at the computer looking at my emails, when I heard from the kitchen, "pitter, patter, pitter, patter..." I stood up and here came Samuel from the bedroom. He was walking all by himself. He started to get a little more courage when Grandma Rankin was visiting and has really done a great job since then. He tries to walk everywhere. That makes me nervous because the basement we live in is all tile.
