I was the oldest of three kids, so I'll admit I never really understood the plight of the youngest child until I had children of my own. As I see my youngest daughter growing up, it is clear that her birth order totally affects her personality. And oh, does she fit pretty much every stereotype associated with being the littlest one. Since she has two older sisters, she's much (much) louder than they are, because she has to speak up just to be heard. She's also growing up faster than her sisters, mostly due to the fact that she just wants to keep up with them. Cue the mini heels and asking to wear makeup! Did I mention she is only 5 years old? If you, or someone you know, is a youngest child, you'll relate to these signs that your birth order really does play a role in who you are, and how you go through life.
