I finally took the kids to the studio and created some great images of them specifically for iStockphoto. My daughter kept asking me "when are we going to dress up and you take our pictures at the studio?". I had told her about my idea several weeks ago. So it was a fun time getting to watch them pretend. Keep watching for more images from this session.
Below are the images I submitted and were accepted. Each image has a link to the iStockphoto page.
