How old is your child - 3yo and just getting into the swing of Christmas, or 9yo and dosn't believe anymore?
Some friends do a 'some people believe in FC bringing presents, some don't kind of thing and Christmas is still lovely.
If your child is very young, as they understand about Christmas and the lights, the lovely food, pantomimes, special food etc, your DH may come to love the festival through your child's joy, not necessarily through the Big Man.
For us, FC is part of the story but 7yo thinks we buy the presents and FC delivers them. We are in Spain where the 3 Kings bring the gifts on 5th Jan, so they don't bang on so much about FC.
For us, it is all about traditions: the tree (same baubles every year, new bauble every year), the food, the festive Skype with faraway family, (seeing those in the antipodes in bikinis and santa hats eating bbq prawns!), decorating the rest of the house, the anticipation of 2 weeks+ off school and new toys to play with, all sleeping in the same bed Xmas night and saying Happy Christmas to the dog (who also sleeps on the bed!), opening the stockings on our bed, the gingerbreadman -shaped pancakes on Christmas morning, putting uolp the stocking, Christmas crafts (lots of loo rolls, pompoms, fingers glued together, tissue paper mishaps!).
For me it is the joy of repeated traditions and lovely hot stodgy food. It isn't as cold here as UK, there isn't wall-to-wall Christmas tv here, last Christmas Day we were watching a Hallowe'en episode of Spongebob
, they don't have the tradition of pantomimes, Queen's speech (not that i'd watch it...!), not many houses are decorated inside or out - my best friend got a tree 2 years ago as she loved mine, she'd never had one in her life, i made her some cute decs for it. Here tbe nativity is massiively important - they take up an entire sideboard and are quite elaborate, children move the kings a little bit closer to the stable every day.
We, personally, don't to Xmas Eve boxes, Xmas bedding, Elf on the Shelf, FC footprints, glittery oats for Rudolph in the garden. Can't be arsed 
But DS still loves Xmas Day and Xmas Eve and Boxing Day and the general excitement of everything. He has presents of course, but not anything excessive and the festival doesn't revolve around gifts. We do birthday presents for others but we have stopped xmas, even for other's dc - that has cut down both stress and tat. What we need we buy ourselves through the year (DH and i will exchange books or small things like stuff for his bike, phone cover for me, etc). Totally stress free Christmas. Oh and we do not host. My family spread all over world, DH's family asshats! We walk the dog twice on Christmas day (as every day) so we get out to blow away the cobwebs. We have Christmas dinner at 6/7pm, not the middle of the day. We eat well but don't over-indulge.
If necessary, tell your DH to fake it !
