The term "mother's son" can be used to describe a male child who is particularly close to his mother, but there are many other words and phrases that can be used to describe this relationship. For example, "mama's boy," "momma's boy," "mum's boy," and "mommy's boy" are all slightly different variations on the same theme. Other synonyms might include "sonny boy," "boy child," "offspring," or simply "son." These terms can be used affectionately to refer to a child who is deeply loved by his mother, or they can be used in a derogatory way to suggest that the child is overly dependent on his mother or unwilling to break away from her influence.
