Teasing is usually mutual and stops when someone shows discomfort or asks for it to stop. It feels light and respectful to everyone involved.
Being mean involves repeated behavior that hurts, embarrasses, pressures, or targets something personal, especially when someone’s discomfort is ignored. If the behavior continues after someone asks it to stop, escalates, or feels intentional or upsetting, it has crossed the line.
If your child is questioning whether something is teasing or mean, that is often a sign that something does not feel right. You can help them name that difference and take their feelings seriously without forcing them to confront the situation before they feel ready.
