on the character of the child. A lot of the differences have to do with how the parents raise the child. If a parent lets their child tell them what to do then obviously the child will display negative traits. This doesnt just go for an only child it goes for a child with siblings also. Whether you are an only child or a child with siblings, your life can be happy. As long as you feel loved and you give love it doesnt matter how your family is made up. It is how you choose to live your life....
