I genuinely mean this kindly, but I think it’s more you than your DD. Kids don’t have that social conditioning yet of a ‘perfect Christmas’ being a parenting goal in life - they just like the cosy atmosphere, the change in routine, the piles of sweets, advent calendars, the lights etc
I have been guilty of this mindset, too, after my kids stopped seeing them one year (and hasn’t since). It’s taken me a few Christmases to realise that the thing that really bothers my children is seeing me be overworked and stressed out. So we aim for fun and silliness, going to see the lights, flasks of hot chocolate, seeing friends, parties.
My kids are of an age now where they don’t genuinely believe in Father Christmas, but they indulge in being silly and getting into it as a make believe/fantasy thing. If we can’t find something around Christmas, we say things like “maybe the elves needed that?” Or “oh no I hope Father Christmas didn’t see me do that!” I also do a little party for a few friends on the last day of term, Christmas treats, mums invited too if they’re cool, mulled wine and Christmas songs on.
I’m not religious at all but we always go to a nativity in a nice church, big walk between presents and dinner too. Now it’s just me and the kids I either do dinner Christmas Eve or I’ll do ready made/ less time consuming food so that they’re not on their own in the day just in a muddle of toys. My ideal is that we all do the building, making, watching telly together without me standing boiling over the oven all day. I also do myself a stocking! Not because I need one, but because my children really love me, and they want to see me have treats too. Again I do a whole jokey thing of ‘ooh how did Father Christmas know I love these bath bombs’ and they sort of eyeroll and laugh but we all buy into it for the craic.
You mentioned your daughter’s safety and I just want to say that you will have a lovely, lovely Christmas, and well done for getting yourself and your daughter into a position of safety and future happiness. I can tell you from experience that the best Christmases ever are the safe and loving ones ❤️
