Kids at wedding

Me and my partner are getting married this September and we’ve agreed that younger children under the age of 10 won’t be allowed to attend. Our children being the exception of course.We’re going to have alcohol and think the older children will be less to take care of constantly. There’s also a couple of children on my brothers side of children who suffer from autism and can’t handle loud music and sounds and we think it’s best to keep them home with someone instead of them being forced to loud sounds and the music is going to get loud. At my brothers wedding they had chairs blocking the door because my nephew kept trying to run out due the noise and I really don’t want chairs in front of the venue doors. So to be fair I’m now requesting older children so my brother won’t feel targeted. My nephew is also a major handful and will destroy decorations. I know some people have an issue with not being able to take their kids but a lot of those parents are also the ones who don’t watch their kids.
