I can understand mixed emotions around this time of year. Loss, bad health, family issues etc which are brought into focus.
However, as a child who grew up with a miserable bastard of a father at Christmas, I'll be damned if my children will suffer the same.
It doesn't have to be over the top consumerism. You don't have to 'do' newer traditions. I don't do Elf on the Shelf or Christmas Eve hampers. It's about mood, some chosen traditions which your family enjoy - it's about the children when they are young.
My father hated Christmas, and he didn't hide it. Ruined it with angry sulks and rows. Made me feel guilty about my presents. Huffed at anything he was bought. Was disdainful of any kind of indulgence.
Don't get me wrong, there are parts of it, I'm not keen on. But I've just focused on what counts.
I'm estranged from my father now and I refuse to traipse round visiting anyone I don't want to. Christmas presents are budgeted but quality and thoughtful. I also dislike behavior bribery which winds children up. Mine have always been reassured that there will be a filled stocking under the tree. They don't need to 'be good' because they are inherently good.
