Sing along Elsa Doll Dilemma

[Twistedheartache]

Help me decide whether I should get DD1 4.9 one?
Pro - She'd be unbelievably excited, it might be on her Xmas list (she wants everything she sees), and she adores Elsa
Con - I feel like it's one of those toys where the novelty will wear off before new year, the noise will drive me insane & she's got other dolls that she rarely plays with

Do you buy what they actually want or what you think they should want?

I'd get it if she asks for it. My niece has one and it's not a bad toy.

Thanks.
Dilemma is we're Santa letter writing/visiting at beg of Dec but I've got one reserved to pick up from argos on Fri/sat coz read it was gonna be like the snow glow elsa from last year & I have just gone back to work ft after mat leave & am lone parent so won't be able to rush around on a mad hunt for one just before Christmas

Buy it now, if she doesn't want it eBay it on the run up to Christmas. All the people who left it too late will rip your arm off for it
