It’s very common for children to disclose first to whoever feels safest in that moment. That might be a friend, a teacher, a coach, or another adult. This doesn’t mean your child doesn’t trust you or that you’ve done something wrong. It usually means they were testing whether it was safe to say anything out loud at all.
What matters most is how you respond now. Avoid expressing hurt or asking why they didn’t come to you first. Instead, center their courage. You might say, “I’m really glad you talked to someone. I’m glad you’re telling me now, and I’m here with you.” This reassures your child that honesty leads to support, not guilt.
