IMO it would be nice for your DC if you made more effort with Xmas. You don't have to follow traditions, you can make up your own.
I remember childhood Xmas as a magical time, even though we didn't have 'traditional' Xmases. We had no extended family nearby so it was just our little family unit, and my parents disagreed with the Christian element so focused on Pagan midwinter traditions instead, and also told us stories from around the world. It was about lighting up the dark winter and spending time as a family unit. We didn't have a roast on Xmas Day, but we'd decorate the table with candles, crackers and a sparkly cloth, and dinner would be in the evening by candlelight, with stories round the fire afterwards. We also had a tree, decorations, stockings, presents and put carrots out for reindeer. And we watched Xmas TV and went for a walk on Boxing Day. At my primary school, Xmas was a big thing and I would have felt left out if my family hadn't made it into something special.
I think children take the 'magical' elements of Christmas and recreate it with their own families. This year will be my first Xmas with my new family. We plan to keep it simple but meaningful. No extended family, no visiting, no stress, no elaborate meals or excessive spending. I'll do some baking, put carols on the radio, light some candles and put up paper-chains and tinsel. The tree takes 10mins to assemble and decorate. We'll each have a few small presents to unwrap, and will take a walk. We might add some new traditions too.
When I think what excites me about Xmas, it's the little things... tree lights reflected in a window, the sound of pine-needles falling onto wrapping-paper, making cards with glitter-glue, collecting pine-cones and painting them, watching the glowing bars of a gas-fire, cutting a chocolate log, looking at the sky on Xmas Eve and hoping for reindeer, playing with the warm wax from sparkly candles... all simple things, but they made Christmas special.
