Laughing can be a survival strategy. Many kids laugh to avoid standing out or becoming a target. Make it clear that laughing does not mean agreement or consent. Reassure your child that the pressure they feel is real and understandable.
Help them brainstorm options that don’t require confrontation, such as changing the subject, stepping away, or talking privately to a trusted adult afterward. Emphasize that their safety and comfort matter more than fitting in during a moment that feels wrong.
