When i was a kid, i had frequent night terrors - i think this is not uncommon..?

Normal phase: Many toddlers and preschoolers have a period of time when they experience night terrors. Although they are very alarming to watch as a parent, children don't typically remember them and are not permanently affected by having them. With time, the phase should pass on its own and everyone will be able to get back to their regular sleep schedules.
