Speedy Gonzales

Yes, the push-up ability has led to crawling. Or, to be more precise, dragging himself forward. Very reminiscent of a war movie hero dragging himself across the battlefield using only his arms, with similar grunting sound effects as well. I managed to catch a few photos of an early sojourn where he really wanted a particular toy: you can see the progression of motion from the top photo towards the bottom photo. This particular journey took a minute or two. Now, he can cover that in 10 seconds. We're not-so-eagerly awaiting the day he discovers that his legs don't have to just be passengers, but can actually contribute to the movement...
