How it's used
Literally meaning not yet weaned from breast milk, this phrase is a sharp, dismissive way to criticize someone for being naive or lacking life experience. It carries a stronger sense of condescension than simply calling someone immature. Use it only when you want to emphasize that someone is behaving like a dependent infant rather than a responsible adult.
Examples
He is still so immature, he acts like a child at work.
Are you still a baby? Why are you acting so childish?

Common mistake
Avoid using this in professional or formal settings, as it is highly informal and can be perceived as an insult. It is strictly reserved for casual arguments or teasing among close friends and family.
