Axel is really crawling now!

Axel is really crawling now.... He is now going forward on all fours (as opposed to just backwards). Go, Axel! Luka never crawled that way, so that is interesting to see the differnces between them. Luka did the special forces crawl (lay on the ground, push with one bent leg, pull with one arm). He may have crawled on all fours one day that I recall, and then went back to his (for him) more effiicient army crawl.
