Definition
One's character is formed at a young age; the child is father to the man.
How it's used
This idiom is frequently invoked when observing a child's behavior that mirrors their parents' traits or when someone's adult personality seems to have been predictable since childhood. It carries a deterministic tone, suggesting that fundamental personality traits are deeply ingrained and unlikely to change significantly over a lifetime. While often used to describe negative habits, it can also be used neutrally to discuss the stability of temperament.

Common mistake
