We decided to have an adult only wedding, but we each have a son from our previous marriages. Is it rude to have our two boys and bridal party children ( 2 flower girls) at the wedding, while not allowing others to bring their children. If we invited all of the guest's children, it would double the size of our wedding, and our expenses. I think it's perfectly reasonable to only allow bridal party children, but my sister says its just wrong. She says people will be upset when they see any kids and we should have no kids or allow all kids. I don't see how people won't understand the space and cost implications of allowing all children to attend. What are your thoughts?
