They dynamics of being a single child versus having multiple siblings in your family is different. You learn life experiences in a different way. Where if you were, like I was, had siblings, you learned how to interact and learned not to be so sensitive, if you got bullied by your older sister or brother. Where a single child may not see that initially. They may not see it for a while. I know my daughter, who is a single child, when she would witness other children that had sisters and brothers, she thought, "I'm not going to have any children because they fight all the time." I explained to her, that I did the same thing with my sisters and brothers. We fought all the time and now they are my best friends in the world. It helped learn life experiences by being challenging with one another, being able to have fights and make up quickly, and things like that. That you learn, ultimately, in real life.
