I have found it fascinating to watch Arthur, determined and strong, learn to crawl.
Working on his rhythm, 5/16/16
Time lapse of Arthur getting around, without actual crawling. 5/17/16
Crawling backwards and getting stuck under furniture. 5/18/16
Pushing to sitting.
Refusing to lie on his back in the tub.
Crawling forward on purpose, with bonus baby sign "milk" at the end, and adorable baby faceplant. 5/25/16
Officially crawling 5/27/16 (6 months)
