A calm, predictable, screen-free wind-down and consistent earlier bedtime help most. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.","answer_md":"*When the night feels like a frightening place, small changes to your child's day can help calm what unfolds after dark.*\n\n## In short\nNightmares and night terrors usually get worse when a child is **overtired, stressed, unwell, or kept to an irregular sleep routine**. Too little sleep, big changes at home or school, screens or scary stories close to bedtime, a fever, or a too-busy, unpredictable evening can all increase how often and how intensely they happen. The good news: most settle on their own as your child grows, and gentle, steady routines make a real difference.\n\n## What tends to make them worse\n- **Not enough sleep** — overtiredness is one of the biggest triggers, especially for night terrors. A child who is sleep-deprived spends more time in the deep sleep where terrors arise.\n- **Irregular bedtimes** — chopping and changing when your child goes to bed and wakes unsettles the sleep cycle.\n- **Stress and big changes** — starting school, a new sibling, moving home, family tension or worry can stir up nightmares.\n- **Scary or stimulating input before bed** — frightening shows, stories, video games or rough-and-tumble play close to sleep time.\n- **Being unwell** — fever, illness, pain or a full bladder can disturb deep sleep and bring on night terrors.\n- **Screens and bright light late** — they delay sleep onset and reduce restful sleep.\n- **Caffeine** — fizzy drinks, chocolate or tea later in the day can fragment sleep.\n\nA calm, predictable, screen-free wind-down and a consistent earlier bedtime are the most powerful first steps — many families see fewer episodes within a few weeks.\n\n## When to seek a check\nMost nightmares and night terrors are a normal part of growing up. Do seek a check if episodes happen most nights, last a long time, involve unusual or repetitive movements, cause daytime sleepiness or distress, continue well into older childhood, or if your child seems to stop breathing or snores heavily in sleep — these may point to something a clinician should review.\n\n## The Pinnacle way\nAbilityScore® is part of Pinnacle’s developmental assessment.
