Why did they keep saying one brother was older than the other??

Kind of a joke between twins.

Same day, different times. Kevin was born first.

We talk about this in the "take care of your little brother thread"

I'm thinking they made Randall the youngest because in their minds he "replaced" their baby who died and he was the third born. But it doesn't seem possible to know what time of the day Randall was born, or maybe even if he was actually born on the same day because he was found at the fire station. How long did he stay with his birth mom before his birth dad assumed care of him, and how long did his birth dad have him before he took him to the station? Could have been a day or several hours. But I can't see knowing to the minute to say if he was born before, between, or after the twins.
