Mine is 7.5 yrs and likes littlest pet shop stuff, bratz and Hannah Montana. Although she also plays with her baby sisters toys a lot too! (peppa pig etc)
At school the 'in' thing at the moment with her and her friends seems to be those toys that come in the shoes from 'Clarks' - can't remember what they are called - Dolls and dogs with little tiny accessories. Also she likes her Nintendo DS (sometimes). Hope this helps?
