First of all, are you buying for a girl or a boy? Second, what do they like or what are they into? Third, if your completely lost for ideas and don't want to risk getting them something they don't really like, a gift they're sure to love is MONEY! That's pretty much all I get now for birthday/christmas gifts since I'm turning 17 really soon.
it all depends on what they like and how they think but I would say girl:dolls make up cutee clothes and us girls like money $ and for a boy:money is all I can say
Girls and boys:
Books: just go to Borders or any other bookshop and ask them what books 9yearold girls like. Uhm, just go to ToysRUs and ask the same question.
FOR A BOY OR GIRL MAYBE A CELLPHONE. IT'S THE ACCESSORY EVERYONE HAS NOW.
maybe a cell,phone a basic one of corse
girl or boy. specify.
A scooter, perhaps??
