As a middle child, I too have not existed for my whole life.

As the youngest child in my family, I was most definitely not "The favorite" but I was able to get away with the most.

Sorry.

Excuse me, but as a middle child, I have to absolutely object to that last statement. Middle children have their own unique sibling/personality complexes. :P

Oh wait, I don't exist. Wow, that's a stealthy, mean joke. That cuts, fam.

An only child is not a sibling

My father always used to say he had three kids. One of each.

30 years later, I repeated this to my niece and nephew. They were quite puzzled. Especially when my brother laughed saying "I forgot Dad used to say that."

We’re always most jealous of the youngest, but actually it’s better for your mind and happiness later in life to be able to handle the world better, and growing up too safe and favorites can definitely prevent that.
