Please don't take this in a judgmental way, because I certainly don't mean it that way! I'm one of 4 and when I was little I used to talk about having ten kids. So I'm genuinely curious. I think it's more normal in America to have 2 kids so people who have 2 kids often don't have as specific of a reason. But most people I know who have more than 2 kids do have a specific reason. I'd love to know yours!
