Milestone: Rolling over already?

One day last weekend I had Zander on his blanket on the floor for tummy time and he used his back legs and kicked himself over to his side then his back. I thought it was just a fluke.

Well, yesterday I put him on the blanket on his tummy and walked to the kitchen to wash my hands when I came back he was off the blanket and on his back. Then today during tummy time he did the same thing, I put him on his tummy and he eventually got himself on his back.

Zander seems to enjoy tummy time. If I put my hand underneath his chest for support he will rock his bottom back and forth on his knees. He kicks himself all over the blanket, he just doesn't have as much arm and upper body strength/control as his lower body yet. I know they aren't supposed to crawl for months. I don't think Zander is even close to actually crawling. He's just not your avarage 6 week old.
