grow down

When young kids think their grown. And it's obvious that their not!

Mom: I can't believe you just said that.
Daughter: Well mom, I guess I'm gettin old....
Mom : grow down, No one says that any more

growing down

when someone grows taller and becomes worse as a person

I feel like my little brother is growing down. He used to be such a sweetheart, but since he's grown to 6'1" he's gotten three detentions.
