When Sydney insists on sitting on her mother's lap, her mother says she is being loving. When Damien insists on sitting on his mother's lap, he is told that he is being a baby. This demonstrates the concept of

Verbal appellation

Explanation:

Verbal appellation, in gender socialization, is a concept in sociology that refers to the act of attaching different labels on the same behavior exhibited by girls and boys. In simpler terms, it involves the use of a specific name to describe a behavior exhibited by a boy, while using a different name to describe the same behavior exhibited by a girl.  

As seen in the scenario stated in the question above, different names are given to the same behavior exhibited based on gender. The mother of Sydney calls the behavior of Sydney insisting to sit on her lap as “being loving”, while she labels this same behavior exhibited by Damien as being that of “a baby”. Different names for the same behavior exhibited by different genders.  This demonstrates the concept of verbal appellation.
