So...my fiance has a five year whom I love very much. All in all, he is a great kid, that is until you introduce his 2 older cousins. I threw my step-son a big birthday party for his 5th Birthday. Unfortunately, his 2 cousins arrived first and began to violently burst all of the balloons that my fiance had inserted glow sticks into and blown up. I asked them to stop and they, of course, ignored me. Then they starteded violently playing with my step-son. No one supervised them and I made my fiance take the reins. My step-son ignored all of the other kids at that the party that were his even his friends to rough house with his cousins.
I was hoping to make my wedding kid friendly, but I know that having Bad Seeds #1 and Bad Seed #2 will ruin my big day. Also, I have out of town friends that I am certain will not come if I say no children.
What do I do?
