Is there an idiomatic word or phrase for the youngest child of a family? It may somewhat have a negative connotation since their parents usually infantilize them.

Best Answer

Your use of "infantilize" provided a clue: the baby of the family.

From the article "Youngest Child Problems: 9 Things Only The Baby Of The Family Gets" by Margaret O'Brien:

Being the baby of the family isn’t always as glamorous as many people think.

For years, oldest and middle children have been claiming that the youngest “gets away with everything” and is “clearly the favorite.”

They have a sort of prejudice against the babies of the family, and it's time the issue was addressed. What they don’t realize is that being the last born comes with its own set of problems.
