Hello all, I (40F) and my husband (41M) have been married 20 years, and our children (twins F and M) are 14 this year.
We decided to get our vows renewed, as we got married at 20 and are now 20 years into marriage, we have spent half our lives together and the milestone lining up with our ages is cute.
We did not have the most grand wedding as we were both college students at the time, and as such have decided to host a more upscale party (not a wedding, we are renting a nice venue and getting a great caterer). It's more for the symbolic value than re-doing our wedding.
We've invited a lot of our family, including my sister (35F) and my brother in law (33M) - they both have young children with their partners (sister's is currently 6, brother in law's is 4.) and we have asked them to not bring them to the event.
We set this rule as there will be drinking, music, and the venue has quite a few areas that are restricted, and we don't think it would be good to have children under ten there with all of us. (we plan on having 23 guests, as those are all that have rsvp'd)
My sister was upset, as the venue has a large garden and an indoor aviary and butterfly raising facility, and her daughter loves butterflies. My BIL was also a bit upset, but more towards finding a babysitter (even though the event is 3 months out as of now)
Well, my sister and BIL have seemed to form a group and, upon learning that our cousin, who has a 10yo, will be bringing the 10yo, they have gotten quite angry and aggressive with us, asking us to let them come with their kids or they won't show up.
My mother is very lax and has on multiple occassions told my sister she's being unreasonable, but my sister thinks "no children under 10" rule should include the 10 year old, and has begun saying she thinks we dislike her daughter.
My husband is quite averse to confrontation and has told me he doesn't care if his brother comes or not.
Meanwhile, our kids are also not helping the situation. My daughter, in trying to be helpful, told my sister she would make a scrapbook of photos from the venue for her daughter, which only aggrivated my sister further. My son, in also trying to help, offerred to stay home and watch both of the kids, which made my BIL start piping up about how my son shouldn't have to stay home because we can't change our rule.
I do want my sister and my BIL to be there, but i also think they're being ridiculous. I have even offerred to pay for babysitting and have gotten turned down. I think they're too far seated in their commitment to getting us to break down the rule than they are to accept a peace offering.
Edit for clarity- My sister and My BIL are not the same family - my BIL is my husband's brother and NOT my sister's husband/partner. I apologize if my wording made it come across this way.
My BIL's wife is neutral, as she has mentioned she would love to attend either way.
