The phrase "little children" refers to young, minor or immature individuals who have not yet reached adulthood. It is often used in a general sense to describe very young age groups, typically between 2 and 10 years old. The term can also be used more specifically to refer to the offspring of someone, such as "my little children." In some cultures or religions, it may have a spiritual connotation referring to those who are innocent in faith and trusting in God.
