I'm in favor of something, almost anything, in a package over something the child has to do, or some gift card, etc.
I don't presently know any six year old girls but I remember being one. I had few dolls or stuffed toys in my childhood (remembering only one sort of stuffed raggedy ann when I was about two, which I probably defenestrated or destuffed, and a couple of others. Didn't get a teddy bear until I was sixteen, from a boyfriend. So, I'm in the stuffed toy camp, though not necessarily a teddy bear. Maybe a fluffy lamb or something.
On the other hand, all six year olds aren't repeats of me; so take that with a grain of salt.
