Hi! My fiance and I got engaged a year ago, and our wedding is this weekend! Our very clearly stated expectation of no children has been in place from the start. His side of the family has 8 nieces/nephew ages 1-10, and on my side there is one 2 year and one 8 week old that belong to my brother and SIL.
Since beginning of this year, my SIL has had the plan of her parents getting an airbnb down the road from our venue, where she can easily pop in and breastfeed the 8 week old as needed. Out of the blue, yesterday (5 days out from wedding) she mentioned he would now be getting dropped off 30 minutes into the wedding, directly after the ceremony, and staying until 9 pm. Apparently during this time period he cluster feeds and it's his "witching hours". During that time, first dances, speeches, and dinner will be taking place.
I expressed to her that we should try and find some kind of compromise to this, and there had to be a better solution to her getting up every ten minutes to quiet a baby and breastfeed. She said she assumed we just would know a newborn would be there and it didn't need to be clarified. She offered to just go back to the airbnb and stay until the baby was down for the night, and return for the last hour or two of dancing. I agreed to this, and apologized for any misunderstanding but stayed firm on our no-kids rule that has applied to everyone.
Today, she is calling family members bawling her eyes out and is very upset. Should I just give in? I feel very pressured and manipulated but don't want to cause family drama! (as a backdrop, she has a history of narcissistic behavior we typically just let her get away with)
