My fiance and I have picked an adults only resort for our destination wedding. My fiance's sister is now pregnant and expecting at the end of February. She's has "mentioned" on more than one occasion that we should really consider changing our venue to a kid friendly resort so she can bring her 8 month old baby to our wedding. She is now very upset with us and saying that she's not going to come if she can't bring her child with or her husband can't come to the wedding because he would stay back with the baby . A few of our other siblings have decided that they aren't going to come to the wedding, but our hometown reception instead to see family and friends. Which we both understand and are ok with. This has been mentioned to my fiances sister by more than just us, but now is taking it that we don't want her to be there. I know we can't please everyone...trust me I know. But holidays and vistits home have now been very uncomfortable, because she'll corner me about it when my fiance isn't around. I try to keep the peace, but end up making her more mad. I don't know how to deal with this situation...any ideas?
