Other than the fact that she doesn't have autism, my lovely dd sounds very similar to your lovely one!
Here is what she is getting in intricate detail, in case it helps:
My DD is quite a mature 13, artistic, a bit alternative, likes rock music, films (especially horror) and anime. I don't have loads of money, but I do spread the purchase of her gifts over several months - I love Christmas and my daughter, and giving her things she will love gives me great pleasure.
We don't do Xmas Eve boxes or anything like that. She does get a reusable advent calendar with little pockets I fill - this year it is mostly anime pins and keyrings; a few other random pins from charities etc; and there is a little animal shaped lip balm in there and a Xmas tree ornament shaped like the animal of her birth year in the Chinese calendar.
We don't so separate stockings so the following are all her Xmas gifts (they will be stuffed into a pillow case).
Main gifts:
Warhammer painting and tools kit
Large Warhammer figure kit.
(She has expressed a desire for this stuff when we did a beginners' painting workshop at a Warhammer store this summer).
Other gifts:
A beautiful book of classic poems illustrated in an anime style (she doesn't want this particularly but I want her to have it!)
A couple of anime books she requested.
The following anime merch (various series/characters):
T-shirt
Hoodie
Towel
Cushion
2x plastic figures
Small plush
Notebook
Art print
Makeup bag featuring characters from a TV series we like
Squid Game top trumps
Squid Game socks
Yung Blud t-shirt
Small bunny shaped lamp from a charity shop
Silver earrings from a charity shop
Black Primark fleece
Small spider plush
A couple of face packs
A couple of fidgets
Fake Dubai Chocolate from B and M
A few random bits for the dolls house she and I intend to do up as a haunted mansion as a winter art project.
She will also get gifts from various members of my side of the family. I don't know what they will all get her, but have asked either my brother or mom to get her a record player, and we are planning to ask my cousin (who never knows what to buy) to get Amazon vouchers.
She will also get separate presents from her dad (we are not together, tho will spend Xmas morning together) and all his side of the family. All I know so far is that her dad has got her some art supplies and a t-shirt.
She's a lucky girl! But she is a lovely person who works fucking hard and has had a brutal year friendship-wise, but has conducted herself with nothing but dignity, compassion and grace in the face of appalling provocation. I would give her the world of it was in my power to do so and she wanted it!
