Caden started walking at 15 months about October 2005. He even crawled before he could sit up on his own....very unusal for a baby. For a while he did the army crawl which was so cute. He also dragged one of his legs. It looked hilarious. He finally figured out how to use both legs to crawl correctly. At this age, Caden also began his love of puzzles. He was very good at them.
