The common and general paranoia that parents often have with their oldest child. They are usually strict and uptight about activities, curfews, and relationships, but once the second child comes around, they loosen up a bit, often frustrating the first-born.
"Hey dude, ya going to the Blink-182 concert?"
"Sadly, no. My mom's got a serious case of first-born phobia."

When in The Sims 2 where you have a kid, exit the game and the next time you have another kid it's the EXACT SAME AS THE FIRST CHILD besides gender....sometimes.

this is all because the game has a selection of faces a kid gets from 1 - 6 and its in that order, no randomisation, overtime you close the game it resets back to 1.
Lets say here that idk Don Lothario and Cassandra Goth start having babies
Don: Hey Timmy!
Cassandra: Bro, thats Jimmy....
Don: THEY HAVE THE SAME FACE, ITS FIRST BORN SYNDROME DANGIT
*Tommy now starts running around*
Don: LOOK, TOMMY LOOKS DIFFERENT TO THE OTHERS BCS THE GAME WASNT CLOSED
