When a toddler engages in intense crying or hitting, it is often because they lack the verbal skills to process 'big' emotions. Maintain a calm, neutral reaction to avoid reinforcing the behavior, and use consistent, short phrases like 'Hands are not for hitting.' Redirect them to a constructive outlet, like punching a pillow or giving a high-five, and consider the 'HALT' method (Hungry, Angry, Lonely, Tired) to identify and address the root cause of the frustration before it escalates.
