I have to find something for my nieces to do at my wedding. I didn't want young children in the wedding so I told my boyfriend's mom that her great niece could not be in my wedding. She is 3 years old. That means that I can't have my two nieces who are 10 and 12 in my wedding because I don't want to offend my future in-laws. What would be a special thing that they could do and feel like they were really involved in the wedding?
