Morten's Chime

At the suggestion of my Early Intervention lady (who is a crazy freaky lunatic and a story for another day), I got a few "musical toys" for Morten.  We got him some wrist rattles and a couple of chimes. 

Here's his wrist rattles - a cow and a pig.  They velcro around his wrists with crinkly straps and have a little bitty rattle in them.

I've been using the chimes with him during tummy time to try and get his attention to lift and turn his head.  Then I have one attached to the side of his crib.  Today when I put him in his crib for a nap, I noticed that he was ringing the chime.  Now, it may just be that he's hitting the chime randomly with his hand, but it seemed to me that it was just a little bit more diliberate than that!  Here's a little video.  What do you think?  Is he playing the chimes for us or just whacking his arms around?
