Child free wedding, but moh has fallen pregnant

Hi all


My fiancé and I get married abroad September 2026. We are having a very intimate adults only dinner party with a dj.
We have always said should we marry we would want our wedding child free. It’s just always been our personal preference. We both aren’t huge fans of children, and at my sister’s wedding the children screamed all through the ceremony & speeches.
We told all our parent guests that it would be a child free wedding. We said should they want to fly out & make their trip a family holiday with children & grandparents, but leave the child with them on the day, then that’s absolutely fine. Everyone seemed happy with it!
Since then, my MOH has told me she is pregnant and is due this September. Her child will be 1 year old come the time of my wedding. I never explained to her about the child free rule as she never had a child, nor did I think she was trying for one. Now, my other MOH has said she isn’t sure if my MOH will attend if she can’t bring the child.
I’m really anxious about having a conversation with her even though she is a really chilled person. I would be so upset and hurt if she decided not to come. We’ve been best friends for 14 years and I was MOH at her wedding too.
We are both sticking to our guns as we really have always dreamt of just an adult only celebration and after all this is our special day.
Does anyone have an advice? Thank you!
