Refined crawling

Big guy has refined his crawling technique. What used to be a half army crawl half inchworm is now an actual crawl. I noticed over the weekend that he was up on his knees. And let me say, that up on the knees crawling is a lot faster then belly crawling. This kid can move! Which is totally fabulous for him. Tough on hubs and I who now have to be extra fast when chasing him!
