my 7 and 6yo dds like:
Anything to do with animals. Real pets (hamsters, rabbit, guinea pigs), plus animal hospital, sylvanian families. Both good as you can add to them for future birthdays and christmas.
Outdoor things - mine like roller skating, skateboards, swingball, surfing, kayaking. cycling.
Anything arty crafty. Things to make, do or paint.
Things to do with dinosaurs/archaeology/history (excavate your own dinosaur sort of things).
Things to do with pirates. especially Girl Pirates.
Books, fact or fiction. My 6yo dd currently loves an Internet linked encyclopedia. I'm surprised but they often like to soak up facts at this age.
Mine DON'T like make up stuff or nail varnish or super-girly-pink stuff. I know lots of girls do but there are a fair number of this age who don't too.
