I was thinking back to the day in HS when my mom told me never to marry a person that was the youngest since I am the youngest of my siblings. I've read this too that generally personalities of the siblings are sort of determined by the order in which they were born.
For Example:
Oldest Childs : they're the responsible ones. They have a feeling of being the provider and taking care of people. Prefers to be right and a little more controlling. Decision makers
Middle Childs : Feels somewhat competitive for attention and will feel unloved more often then the other children. They often feel life is unfair.
Youngest Childs: expects others to make decisions and take responsibility. Will often behave like an only child.
Only Childs: Often enjoys center of attention and can feel incompetent compared to adults.
