She'd probably love a lego set and they have such a wide variety these days! From what I remember, she enjoyed doing the lego dots kits they got when they did a sponsor. One problem would be transportation as, speaking from experience, they can break easily. Not that that really matters cos they don't take stuff with them when they go
But otherwise, defo a game! There are such a range of these too. Something like buckaroo, pop-up pirate, or they could literally just search her favourite animal for instance and gets 100s of games around that.
At her age I was still playing with dolls, doing lots of arts and crafts, etc. Yes I got clothes, money, etc. (It was the b-day I got my 1st, very very basic phone too) but I very much still got toys and fun things. She is still a child and they want her to grow up fast imo since having the youngest 2.
Let your 11 year old act like an 11 year old!
