The following is excerpted from an online article posted by Parents
The “good boy” trend boils down to this: a child instructs another to complete a task and when the child complies, the kid responds by calling him a “good boy.” Typically, kids will say “good boy” in a patronizing and dramatic tone, sometimes it’s even topped off with a fake smile or slow clap.
Kids will also say “good girl” in the same patronizingly slow way that they say “good boy.” In either context, the phrase is not intended to be said as a praise, but rather to mock the child (and sometimes adults) for their amenability.
While opinions remain divided among teachers and students on the severity of the “good boy” trend, it’s still a conversation worth having with your child. On one end, children shouldn’t internalize the concept that helping others and following directions is something to be embarrassed about. On the other end, as one student put it, perhaps “it’s not that deep.”
So instead of punishing them, sit them down and make sure they understand the implications of what they’re saying and how it can make others feel. Help them to understand the bigger picture—and hopefully, their classroom won’t sound like a dog park next time.
