No children at wedding

So I got engaged.. yay me! Lol now that I’m thinking of the wedding and guest list I started thinking about doing no kids or at least 15 years old. Has anyone done a wedding where no kids are allowed? If so, how did friends and family take it? I wouldn’t mind kids but a lot of my aunts and uncles kids don’t know how to behave. I know they’re kids but at events like this it’s just respectful to behave and it’s kind of expected but they’re not like that. I just worry that many might not come because of this rule. Also has anyone done it where the bride chooses no children from her side of the family while the groom chooses to have children? I know it sounds complicated but i just want to hear other people’s perspectives. Thanks in advance ☺️
