I'm planning my wedding for next year and my fiancee and I have decided to do an adult only reception. My siblings have kids that will be 8, 6, 3 and 1 by the time the wedding rolls around. My fiancee's sibling has a child that will be 3 by the time of the wedding. All the nieces and nephews will be apart of the wedding ceremony as Flower Girls and Ring Security. However, we do not want them to come to the reception as we feel the parents need a night off to enjoy themselves. Our problem is that my siblings along with my parents are hell bent on fighting us to let all the kids come. A little backstory, my siblings rely solely on my parents for child care because their in-laws are incapable or outright refuse to help.
Can anyone give us any advice? The arguments have already started and my fiancee can't be happy or get into the engagement mindset because we're so stressed out about this.
