First, take a breath — you're doing your best, and that matters. During a meltdown, the most helpful thing is to reduce stimulation: lower your voice, dim lights if possible, and give your child space without leaving them unsafe. Avoid reasoning or lengthy explanations in the moment — their nervous system is overwhelmed. Once they're calm (which may take 20–40 minutes), then you can reconnect gently. Would you like help identifying what might have triggered it, or strategies to prevent future ones?
