@FuzzyPuffling absolutely don't mind that one bit - each to their own! But I'm not forcing anyone to send one back, or forcing them to frame the card and create a small shrine to my child in their entrance hall!
I also have absolutely no issue with the idea of the recipients opening the card, rolling their eyes and saying to each other "good grief Jetset is such a Christmas loving saddo!" (everyone receiving a card already knows I'm a massive Christmas loving saddo), or "good grief look at this! that Jetset just loves her kid TOO MUCH!" (You're damn right I do!) so I fail to see the harm!
As I said, I got about 15,000% more joy from doing a little photoshoot, seeing the final pic, writing the cards, and seeing the few friends I've already given them to opening them and say awww, than I got from writing generic Sainsbury's xmas cards as I have done for the past 3 years... and frankly that's a good enough reason for me!
In future years I look forward to whole heartedly embarrassing my child with my over-enthusiastic approach to Christmas and to her, just as my mother did to me, and providing her with a shoebox of shameful Christmas card photos to look back on and laugh at when I'm dead.
(By the way some people have already opened the cards because I had to do "xmas in October" with some long distance family that we visited last month... I'm not THAT a much of a Christmas loving saddo!)
