Everyone told me that I should have another baby after Justin, I said "No thanks." They said Justin would be like an only child because of the age difference between him and the kids. I knew he would have cousins to bond with and he does. He gets along great with his cousin Russell that is only a couple of months younger.
Even though his brother, sister and cousins are older they always include him in all that they do. He isn't missing out on anything. I don't think he feels like an only child.
