I'm sure the idea of whether or not birth order can affect your personality has crossed your mind a time or two -- and honestly, it looks like it might have more of an influence on how we (and our kids) act and conduct ourselves than we thought.
According to some researchers, it all has to do with the fact that moms and dads parent each child differently, which means kids wind up taking on different roles in the family -- giving them their own distinct personalities.
It turns out that most kiddos fall into one of four categories when it comes to how they act based on when they were born.
Take a look at these photos to see which ones fit you and your kids -- and to see if they hit the nail right on the head!
