Taft has started to do his version of a crawl. His nurse called it the army crawl and that is exactly what it looks like. When he pairs that with his rolling ability he can cover a lot of floor in a very short period of time. It's hard to do a lot and keep up with him at times. He doesn't always like to be put in his jumper of high chair for mommy to get a shower or cook so we bought a play yard. The play yard gives him a lot more room to roll, crawl, and play than him being in his play pen part of his pack and play. He really seems to like it and we love it. Now - if I can only get Shane to not call it a cage.
