Me and my siblings want to celebrate Christmas again but our mom won’t let me.

We’re all Christian but my mom has been trying really hard for us not to celebrate anything, we did do thanksgiving tho this year. I’m just a bit confused by her views but I do understand the pagan traditions celebrated and how it been getting more and more expensive. I don’t even want presents if we were to celebrate it again, I just want a nice tree and to be cozy in the house with that Christmas feeling again :/

What’s your guys take on this?
