I'm at the beginning stages of planning my wedding and we are on a tight budget, I'm trying to keep my guest list to 75 people. I was wondering if it would be rude not to invite children of some guests. I was planning on having only my niece and nephews there, they are not part of the wedding party, but they are family. Do you think that other guest who have children would be upset cause I allowed those kids and not theirs? Any advice would be helpful, Thanks!!
