The youngest always gets a bad wrap as the spoiled baby who gets away with anything - and maybe that's true.
Many parents are much less stressed after getting some parental practice with the first few offspring.
By the time the last one comes around, they may just let the family baby do something that once was incomprehensible, such as eating something that fell on the floor, or - gasp! - letting the dog lick the youngest's face.
And because the parents are more relaxed, research shows the youngest usually are too.
That is evident in a British study, which shows that the youngest believe they are their parents' favorite, the funniest, and more laid back, while the eldest feel they are the most responsible, successful, organized, and self-confident.
One study shows the youngest child is more adventurous by having to find a family role that hasn't already been claimed by previous siblings.
That's why the study's author, Frank Sulloway, believes the youngest are more exploratory and creative.
In fact, a 2011 Career Builder study shows the youngest tend to choose more creative jobs, such as "art/design/architecture, editing/writing, information technology, sales," while the eldest are more likely to choose a field in government, information technology, engineering or science.
(And, middle children, if you're feeling left out, Career Builder states you are more likely to take a job in law enforcement, fire-fighting, construction, or education. You're welcome.)
By having to find their place and compete for attention, the youngest typically ends up as the family comedian.
Sure, research shows that the oldest child might be the smartest, but research from YouGov also shows the youngest siblings feel they are the funniest.
And since laughter is the best medicine, they're basically doctors...Right, youngest siblings?
Kevin Leman, who authored the children's book, "My Youngest, There’s No One Like You," lists several comedians who are the youngest child in their family, including Billy Crystal, Eddie Murphy, Jim Carrey, and Ellen De Generes, just to name a few.
However, if you're not a fan of the stereotypes that come with your birth order, feel free to take it all with a grain of salt.
Another study on more than 375,000 high school students showed birth order had minimal differences on one's personality.
No matter your birth order, just be glad you have a sibling.
According to research, your annoying brother or sister could actually be good for your health.
