FG Dilemma

So I finally asked my cousins to be in my BP. One of them is my MOH, and the other is just a BM. MY MOH has twins that I wanted in the party too. My other cousin has 3 kids, and I was only going to ask her oldest because my FH has a cousin the same age and it would have been perfect.

My cousin just emailed me and said she doesn't want me to ask her oldest because she doesn't feel it's fair to have one and not the other. Her youngest is too young and ill-behaved to be in it. I asked her if she minds if I still ask my MOH's twins to be in it. I don't want my other cousins children to be upset that they weren't even asked.

What do I do? Should I just not have any FG or RB?

I think you should definitely have a FG & RB even if you can't have everyone's kids in it, you should still have them if it's something you want......people should understand that it might be a lot to have 5 kids in the bridal party...and that it really should only be up to you & FH whether you want to have 2 kids or 10.

What are the ages of all the kids? What did your cousin say when you asked her how she would feel if you asked the twins to be in it?
