T.T.
I just got my boys a new toy that I think would work for either a boy or girl. It's called a kididoodle by VTech. For $30 you get two handheld devices. They can draw on them, select ecards or play games on them. The cool part about it is that they play each other and send the "emails" to each other. A friend recommended this to me and her boys love it and now my boys love it too.
Another idea is that most kids like Webkinz by that age. I'd say most girls like them and a lot of boys do. My older son, who NEVER showed and interest in stuffed animals LOVES his.
For girls Groovy Girls seem to be a hit, especially the horse. Of course a lot of them like the Pet Shop toys.
