[RANT] Future MIL is forcing me to have children at my reception.

I'm am beyond sick and tired right now. For months on end my fiancé's mother has been saying that we have to have children at the reception. Its apparently not optional for her. She insisted initially that it was one child. The toddler of my FH's eldest half sister. Now she's demanding that FH's niece and nephew go as well. (They're almost 10.) I've tried to explain it to her but she just won't give it up. (E.g. "If I invite so and so's children, it won't be fair on the other parents. They'll be upset with the fact that I allowed so and so's child/ren to go. Plus if I allow just one everyone else will be asking me too.") A fair few of my own family have children and even my 11 y.o half brother isn't going. I don't want kids there - not in the reception. All she does is complain that if they can't go she'll have to not go and babysit them. Either that or she tells me "it's hard to find babysitters these days". I don't know what to do, I'm beyond dealing with her. FH doesn't want a child-friendly reception either. We've considered hiring out a hotel room for the night and hiring a babysitter but it's proven to be difficult and rather expensive. We're okay to have a child friendly ceremony but that's as far as I'm willing to go. My partner and I are pretty much the sole funders for the wedding as it is and all we get is her bitching!! via /r/weddingplanning http://ift.tt/2tR0En5
