I get married next year. My fiancé and I had agreed we don't want children at our wedding other than initial family which are his neices and nephews. He has 8 neices and nephews with one on the way. His neices and nephews will be aged 6-21 at the wedding, all are part of the wedding party (bridesmaids, flower girls, page boys and saying readings during ceramony). His sister is having someone babysit their newborn as she too didn't have young children at her wedding and suggested to me that she'll ensure she has someone to watch baby.
Now for my dilemma: my maid of honour (best friend of 25+ years) feels that her son who will be 2 years old at our wedding should be invited as he is the same to me as my fiancé's neices and nephews. I've explained that it's family only children considering the price of the venue/meals and at 2 years old he's significantly younger than the kids invited. She's said she cannot believe he isn't a page boy and I am a disgrace. I've been accused of allowing my fiancé to dictate this whole wedding because his family are involved. I have a very small family, I'm an only child as is my father and my mother. If I invite my best friend's son, my fiancé's best man has 5 kids - 3 of them under 5 years of age. None of this was what I wanted for my wedding day. Its an expensive venue and we already have quite a large number of guests, we can't afford to add on another 9 children. I have tried to explain all this without any success.
She has told me over Christmas might I add that if her son is not invited she will not be my maid of honour and will not be attending my wedding. I am absolutely heartbroken. Our other friend and my other bridesmaid is involved, she has made it clear she agrees with MOH. Am I being unreasonable? I don't know what to do.
