Is it ok to have different rules or circles of invitees for the different familys? I am inviting all of my first cousins as well as their children since they all have small families and we are very close. My FI wants to invite all of his Aunts and Uncles but only the older cousins since one family has 7 children and we are not as close to his cousins (none of the cousins have kids). If we do this should we cut off his cousins at a certain age? or should we just invite them all since there will be children from my side of the family there? I don't want to upset anyone but it gets really expensive with a family of 9.
