Baby-F turned 1 today! And Big Boy announced: “He is now a brother!”

I was puzzled, and responded: “But he’s always been your brother, even before he was 1 years old”

But Big Boy explained to me with exaggerated patience: “No, but when he was 0 years old, he was a BABY brother. Now he is 1 years old, he is JUST A BROTHER!”

Oh-kay.
