re: When did your toddler....

DD took her first steps at 9 months and was full blown walking by a little after 10 months. I think the only reason she took off so fast was because she wanted to chase after her older cousins. She stopped crawling soon after that but sometimes when she is being silly she will crawl on her hands and knees and giggle the whole time.
She is 19 months now and thankfully stays next to me when she is walking in the grocery store.
