AITA for getting angry with everyone

I am 27F. My fiancé is 26M and he’ll be 27 in December. We have a daughter together, she is 2. My parents are divorced and have been for years, they are on good terms. I am the baby and have 4 older brothers and 2 sisters. It’s always been crazy but it works.<br><br>Here is the issue. My parents are divorced and I want my wedding to be intimate. I have a lot of family and I don’t want my wedding to be a family reunion. We have almost no contact with my dads side of the family, and we are not inviting them. I wanted to keep it to parents, grandparents, siblings and their spouses. All of my siblings are over 30 and most have children, I wanted to keep it simple and not invited the grandchildren. <br><br>My mom was very understanding and so were my grandparents too. My dads side of the family are very upset. They are mad that I would exclude their kids/grandkids from the wedding. I have one brother who has 3 kids and his sisters (my sisters) have 3 kids in total. I am still firm in that I don’t want kids at the wedding. My dad argued that I should let their kids come, since my fiancés family is not coming. <br><br>My fiancés family lives overseas and while invited, they are not coming. His father is not well and his mother does not travel. I have not spoken to my fiancé’s family in person since I was 16. We Skype and keep in touch and I like them very much. <br><br>My dad is arguing that I should let his grandkids come, since obviously children are allowed when my daughter will be there. I am getting married in October and I won’t have my daughter flower girl or anything, but she will be there. I am arguing that she is MY child, she is also going to be there because she is my child and she has nowhere else to go when she is 2.<br><br>I want to add that my daughter is the only grandchild on my mom’s side, and she has 9 on my dads. I am the last of the “weddings” since all of my siblings are married. I think this is why my dad is being pushy about this. He wants to see all of the grandkids get involved since mine is the only wedding my mom will get to see in her life time. She has already seen 7 weddings on my dad’s side. <br><br>AITA?
