We are surrounded by "perfect Christmases" whether that it is advertising, TV shows, daytime TV, kids shows and books, magazines and newspapers and it's all directed at women and mums and their dc. It's all about "the best Christmas ever" and it raises anxiety as we're in constant competition with ourselves.
Men don't worry about this stuff in the same way, well not ones I know. My dh actively dislikes it and had only put on a front since having kids and when I mean a front he will watch them open presents and cook a roast but that's it, left to him there'd be no tree, no stockings, no activities etc I think he would get the kids a present but it would be just like birthday nothing more.
I do the rest and generally I like it, but I get the dready feeling too. It's the expectations. I ruined Santa one year by going in when eldest woke up although he's got over it!
I also worry about bad stuff happening "because people can't die/be ill at Christmas" which is ridiculous I know, two of my own relatives have died on new year eve. It'd be devastating whatever time of year, I think that stems from years back when a young mum died of swine flu on Christmas Eve and I couldn't stop thinking about her young children who were waking hoping Santa had been and finding out mum died
