Toddler Days

I guess I officially have a toddler now...what is the exact age when they become one?  Whitley Claire doesn't crawl at all anymore :)  It's so cute to watch her walk around and I am LOVING her being able to walk.  You always hear that once they start walking, they get in to a whole new level of trouble..but I am really enjoying her being able to walk. I don't have to carry her everywhere. So my back and wrist doesn't hurt that much! She had fun walking around in Home Depot tonight going up to everything and touching it. So cute!
