Family
You and your family are first and foremost in shaping your child's development. While friends and other non-family members certainly have a swaying impact, the immediate family is typically the most influential interpersonal factor when it comes to kids. Your child's behaviors, what he finds acceptable and not acceptable, likes and dislikes and norms, all come from the family. For example, if talking during mealtimes is a staple of a family's behavior, the child will most likely act like a little chatterbox in almost every eating situation.
