A disposition that generally arises with the middle child of three children in a household. Middle children often lack the attention that the oldest (the most important child) and the youngest (the parent's favorite child) receive.

Middle child syndrome is often characterized by: lack of friends (a loner), inability to maintain relationships, extreme creativity (writing, music, art, etc.), an easy going personality, trouble choosing a career path, trouble maintaining a career, quick loss of interest in things, negative outlook on life, half-assing, and indecisiveness. Famous middle children include David Letterman, Madonna, and Richard Nixon. Need I say more?
I am a middle child. I suffer from middle child syndrome. Therefore I am creative in writing this, but also extremely middle child-esque for writing this melancholy piece.

an emotional scarring condition.
Middle children are known for ending up with the things that are too big for the baby in the family and too small for the oldest.
it is a known fact the youngest and oldest are treated differently than the middle child for the oldest is the first child aka favorite
and the smallest is the baby aka the last child known for getting whatever they desire because they are the "baby"

Middle Children sydrome includes
neglect, forgotten dates, and sometimes in bad cases forgetting they even exist.

i lived through this condition,
it is not fatal
just difficult.

Middle child syndrome is something that I go through... it’s hard. The oldest child is the one who is most dependable in the parents eyes. The youngest is the sibling who is an attention seeker, and with that they get attention. As the middle child, you are always forgotten, not noticed, have a little to no self worth. We usually become very social people and have a large group of friends. But, people will make assumptions about you thinking you have the best life ever, so whenever you talk to one of them about it they deny everything you tell them or call you an attention seeker. The quality’s of a middle child consist of huge creativity, social, antreverts, but are very much introverts towards their family. I’m a middle child, so I know all of this is true.
Mom: Kelsey (oldest) come here!
Kelsey: What did you need?

Mom: I got you a new phone!
Kelsey: Omg mom, thank you!
Mom: I got you a new phone to, Addie! (youngest)
Addie: Thanks, Mom!
Mom: Sorry Layla (middle), I couldn’t get you one.
Layla: It’s fine....

This is a purifyed example of "Middle Child Syndrome"

A child in a family is neither first or last is called the middle child. In a 3 child family, it is the 2nd child, etc.

This child usually gets the least amount of attention, because he/she is not the parent's first, and not deemed as 'special' enough, and is not the parent's last, and so is not treated like the baby.

This creates social tension between the family. The middle child would be the outcast while the rest of the family can have a laugh with each other.

However, in a family where there are seperate parents, creating half-siblings, where the child is in the middle of one side of the family, and is the first or only child in the other side, the middle child may become brattish, and demand everything he/she wants because he/she can get away with it with the other parent.

In the case of bratty middle children, the oldest usually looses out and then becomes the outcast, being independant and deals with how they recieve less attention than the middle child.

A terrible syndrome in which one is born after someone, but someone was born after them as well, making them the in between of their siblings. The only known cure is MURDER, and it NEVER fails. Most common symptoms are crying, being easily annoyed, and being tall BUT not as tall as the oldest child. If you have this or know someone who does, call your doctor or therapist IMMEDIATELY.
