Night terrors, where a child wakes up screaming loudly and is difficult to console, are a common developmental phase, often triggered by overstimulation, fatigue, or stress. Unlike nightmares, the child is often not fully awake and may not remember the event. The best approach is to remain calm, provide a quiet and soothing presence, and avoid fully waking them up. If these episodes become frequent or distressing, ensure your child is getting consistent nap times and minimizing over-stimulation before bedtime.
