My dds are either side age wise to your dd but some ideas. Ive got dd1 13 and dd2 9.
Dd2 is having a proper styling head like hairdressers use with a tripod and a variety of accessories. (Does come with a clamp to use on a table too). She loves dolls particularly trying out new hairstyles which she then does on me or herself so thought this could be a winner.
Dd1 loves sketching and drawing so she's having a box with all she needs and possibly a fold up easel.
They both like squishmallows soft toys, fleece blankets, and bits for their rooms.
Dd1 is getting into baking and is obsessed with baking programmes, so I'm putting together some bits for her with some printed recipes. (And the ingredients for Xmas day!)
Dd2 is having a beauty box filled with nail varnishes, those beauty face masks that look like different animals, body glitter. Looking at the UV lamps to dry the nail varnish, a headband for the beauty masks. She would love a dressing table with light up mirror but saving this for her birthday next year.
How about a sewing machine? She could make clothes for her dolls that way but won't be outgrown as she can use it to make other things too.
I made a surprise box last year for dd1, filled with funky printed clothes, tshirts, film merchandise. Kind of like those geek boxes but tailored completely to her!!
A subscription? Dd1 would love a crunchy roll subscription to watch endless anime. But loved her phoenix comics and beano ones. You can do baking ones, arty ones, magazines, if you can name it there's probably a subscription available!!
