Yeah, that's the only actual one. There's no definite biological trait though.

For me it's the same thing because I'm the oldest.

I've gotten punished for having panic and anxiety attacks, for crying, for being mad about something because I need to be a "good example"

... Yeah probably. In my family being the middle child would be the best.

Being the oldest means you have all the responsibilities, you're not allowed to cry, be angry, or have panic attacks because you need to set a "good example" for your younger siblings. You get the harshest punishments because you're supposed to know better and you are the experiment child so you will probably have a worse childhood than your younger siblings
