Planning a wedding for next October and my Fiance and I have decided not to include children. I made this known to my sister immediately after we got engaged and her first response was "well then we won't be able to come". Our wedding is not kid friendly and we have lots of friends with kids that are taking the news well. How can I respect my vision and maintain my relationship with my sister and have her attend? The wedding is on a Tuesday night (our 8 year anniversary) and dinner wouldn't be served until after the children are in bed. Please help with ideas.
