I'm having the same problem with my 10 yr old - she is very grown up for her age & has just had a birthday where she got a guitar, clothes & blackberry from us & others.
She totally grown out of toys, has plenty of arts & craft stuff , TV, household iPad etc so this year it's proving really really difficult - the ONLY thing on her list so far is a Lipstick mirror for her newly decorated room - but she wants a lime green one, which so far doesn't seem to exist
& she loves books, but is very fussy about what she reads at the moment, so not sure I could safely choose for her - same if we bought her more clothes or shoes, she's a nightmare to shop for - her GPs are looking at paying guitar lessons for her
Though I have just got her pinning stuff to a "all I want for Xmas" board on Pinterest, so I'm hopeful for my ideas that way - would that be an idea for you to try sweet ??
I am liking the look of the Animation studio though Viva she's very arty so that's something I think she would enjoy - I now just need to find out if its compatible with our computer - we are on MAC mini, which isn't listed on the ad
I had also thought of looking at metal detectors, she loves beach combing for sea glass, but I'm not sure - she is so fickle it's unreal
fingers crossed her pinning on Pinterest brings results
