Navigating Sleep Disturbances

As children grow, they may experience occasional sleep disturbances, such as nightmares or night terrors. Understanding the differences between these events can help caregivers respond calmly and effectively.

Nightmares vs. Night Terrors

While both can be distressing, nightmares and night terrors occur during different stages of sleep and present differently:

  • Nightmares: These are bad dreams that typically occur during REM sleep, often in the early morning hours. Children usually wake up fully and can often recall the dream.
  • Night Terrors: These occur during deep, non-REM sleep, usually in the first few hours of the night. A child may appear awake and agitated but is actually asleep and will likely have no memory of the event the next day.

Supportive Responses

  1. For Nightmares: Offer comfort, reassure the child that they are safe, and help them settle back to sleep.
  2. For Night Terrors: Do not try to wake the child. Ensure their physical safety, remain calm, and wait for the event to pass naturally.
  3. Consistent Routines: Maintaining a regular sleep schedule can be associated with a lower frequency of sleep disturbances.
