No idea. She loves dolls but already has two American Girl dolls. She'll get a doll outfit or two, including a matching one, but I'm stuck for a big gift idea. I had thought about a sewing machine so she could learn to sew dolls clothes. But she said she doesn't want a sewing machine. (Also, I don't have a clue how to use one so I need her frustration tolerance to be high while I figure it out too. So, she really needs to want one. I'm filing this idea in my brain for a later date though). There's a chance she'll get another American Girl doll as there's one she keeps looking at and hasn't come right out and said no. Or yes. But not a no is the best we're doing right now.
As for Roominate, she got that last Christmas and does enjoy it but doesn't want any additional sets.
At one time, there was a
Lego Friends set she wanted, but she changed her mind.
At one time, she wanted one of those yard geese with outfits to change it. But she also changed her mind.
She loves Minecraft but doesn't want any Minecraft stuff. She doesn't play other video games.
She's always been my hardest to buy for, no matter what the age. She doesn't want much and gets overwhelmed when she has too much. That's usually a good thing but not when she doesn't have Christmas ideas! Last year, her big gift was a night at a hotel with an American Girl package and going to the store and picking out one outfit. So, also think about experiences to further your options.
My daughter's last birthday gift was a floor beam. So, if your child is into gymnastics at all, a floor beam could work as an idea. We got one that folds up. The regular beams were way too expensive. Plus, this way, I don't need to supervise as much!
