My fiance and I do not want to have kids at our reception. However he has like 10 first cousins, most of which are 12 and under. His mother has been arguing all the reasons first cousins should be invited, and though she won this argument months ago by saying she'd pay for the kids. That's not the reason we don't want kids (although we do need to save $$)...kids can be wedding ruiners. So today I said something about us not inviting kids and she blew up on me... She's so disappointed in our decision blah blah blah and now she is not speaking to me. Should I give in and invite all the first cousins, even though they're bad and will definitely drive me crazy, or should I stand my ground? This is seriously making me sick
