Children grow up – they get older, bigger, and more mature:
▶️ I grew up in a small town where everybody knew each other.
▶️ Your kids are 12 and 14 already? Wow – they’re growing up so fast!
We usually use grow up only until kids become adults around age 18. After that, we
can say they are all grown up (meaning they have finished the growing up process).
Saying that an adult needs to grow up means they are acting immature, like a baby
or child, and you want them to act more mature.
Parents (or other adults) bring up the children. The expression bring up can have
the connotation of both caring and educating. An alternative word is raise:
▶️ My parents brought me up to be polite and respectful.
▶️ = My parents raised me to be polite and respectful.
▶️ Henry’s parents died when he was young, so his grandparents brought him
up.
▶️ = Henry’s parents died when he was young, so his grandparents raised him
Bring up and raise are often used in the passive voice:
▶️ I was brought up to be polite and respectful.
▶️ = I was raised to be polite and respectful.
▶️ Henry’s parents died when he was young, so he was brought up by his
grandparents.
▶️ = Henry’s parents died when he was young, so he was raised by his
grandparents.
