Ha! My step sister got married when DD was three weeks old and it was child free and she was not invited, I declined.
I can see how people might prefer no children of course but I failed and still fail to see how DD would have gotten in anybody's way.
I was expected to put her in a hotel 800kms from home with a babysitter from an agency. Wow, actually it still makes me upset seeing how we are 'family' and all that.
