So here's the situation! I am getting married in January 2010, and am starting to look for a dress. There's a bridal gown sale in September that I want to attend with my mom. We live in Lexington, KY and the sale is in Louisville, which happens to be where the future in laws live. I want to ask my future mother in law to come because I think it would make her happy to feel involved (she's bummed already because we decided to go to St. Thomas by ourselves to get married). However, the future sis in law lives in Louisville too, and I am afraid if I ask my fiance's mom to go that it will be expected that the sister in law goes as well. I like the sister but she is VERY opinionated. She also has a 4 year old and a baby and I definitely don't want to deal with the kids. I could probably put up with the sister if the kids didn't come, but her husband works evening shift... Is there a tactful way to say, leave your kids at the sitter?
