I've never been too keen on the thought of having kids at my wedding (other than those that are in the bridal party, or are children of bridal party members), but it's become pretty unavoidable, and I've come to terms with it. Many of my cousins have kids that will be attending, and whenever they get together are completely out of control. One cousin, in particular has 4 kids, 3 of which are under 7 and don't behave well in public.
Is it acceptable to put on our wedding website that we would appreciate if everyone could keep their kids under control during the ceremony? Obviously, worded nicely and assuming everyone visits the site. We plan on having a quick ceremony, probably no more than 15 minutes. I'd like to think this is an acceptable amount of time for kids to sit still and behave, but I'm worried that won't happen.
I know it's popular to have a child-free ceremony and only invite them to the reception, but I really want my cousins at the ceremony as well. Some of my older cousins have kids that are in high school and are plenty capable of looking after the younger ones, but they're pretty immature and I don't see that working out.
Any advice?
