oooh great shot =) nicely done!
hey rich, I'm not sure how pix will turnout, but try this:
Shoot at "her" eye level. When you're taking pictures of your girl, just stoop all the way down so the camera is exactly eye level with her. This might give a more of a "personal" feeling, rather than a "overseeing parent" point of view.
If you get a shot of her at eye level, it will make the viewer feel that they're basically interacting with her, or the viewer will feel like a little kid again (though I feel that way all the time regardless).
The photo above is neat, but it has a "parent view" to it. If you got down low for most of your shots, I think you'll get a really cool perspective.
Again I've never tried it, but it's something I've noticed about pictures of children that I think might be awesome.

You know in portrait photography? One of the major rules is to never take a shot ABOVE a standing person. Usually eye level is the rule of thumb. Of course there's some glamour photography where a girl is laying down or something like that, then that's different. So I'm thinking, for kids it's hard, because they're so low to the ground (naturally). If we got eye level, maybe that'd change the entire shot and make it feel more personal, and that perspective might be really cool!
Try it out if you're interested and post some results. It might be hard on your back and legs, but hey, I know you're an athletic guy

it's the struggle of taking the shot that counts!

I've taken shots from above:
but I didn't like that one, first of all her eyes aren't on the camera, and I'm way too far up. Then when she was sitting, I got exactly eye level, and it made a huge difference:
of course one can argue that those two shots are COMPLETELY different in all aspects except the model is the same, but you can see the perspective changes a lot. In the second shot the model is sitting fairly low, and getting eye level definately gives a good perspective. I wish I had a shot of her when I was standing straight up in the same pose to show you =/

here's one from below:
and one from above:
you can see the drastic perspective changes. So definately try it with your kid =) Straight on shots, and maybe some from below.
GOODLUCK! be sure to post your results for us to see =)
