Rant and advice needed
From the beginning we said no kids at the wedding - we gave all siblings a year and half to find a babysitter.
Everyone did but one- we get married next weekend and looks like she has no intention. We have asked multiple times why she can't ask certain people and just excuses. I don't know how to handle this as his mom doesn't see why she can't stay. My sister has paid for a babysitter (she as a three yr old and twins who are 8 months) and the girl drives few hours to stay for the weekend so my sister and my brother in law can help set up on friday, attend rehearsal, and stay with us night prior (their choice for staying) then we have a early 7am start for makeup 8am for hair and she lives 45 minutes from where we are getting ready
I said the kids could attend ceremony, dinner and leave directly following dinner. FH's other sister with three kids got a sitter who is picking them up at venue. His other sister who has one kid who is turning two shortly has not and doesn't look like she is going to. When discussing it she said worse comes to worse she can leave- I just think when comes down to it she will stay- her kid is a brat specially at night and won't do well.
How else can I approach this? Or what else should I do? We are not making an exception for her or I would of told everyone they could bring their kids.
