Ha ha! This reminds me of the time that my friend's DS asked for a penguin for Christmas. My friend presumed he meant a cuddly toy and went along with it when writing to Santa until it came out that he actually wanted a real penguin!
She did manage to let him down gently in the end and I think she got him a zoo membership and got Santa to write beforehand saying that he couldn't deliver live animals as presents.
Anyway, it was a palaver but it didn't ruin any of the magic of Christmas for the little boy in question. So don't worry, this won't for your daughter either 😊
I'm sure you'll swerve the £1,200 gift no problems... I'd probably say that It would be too heavy for the sleigh and I've seen a better one that has its own white horse/unicorn (as per the smyths toy shop one). I'd also do whatever I could do (maybe something you could do with parent controls???) to stop her from ever seeing that YouTube video with it in again 😂
