So nightmares and night terrors are two very different things. When a baby or a child falls asleep, usually within about 15 minutes or so they are going into their deepest sleep of the night. And that deep sleep cycle usually lasts maybe 45-75 minutes. So like an hour or an hour and a half after they fall asleep. Then typically they transition into a lighter stage of sleep. Often, young kids will wake up or seem to wake up screaming at that point. They won't recognize where they are. They won't recognize you. That's typically a night terror. They're not dreaming. They're not having a bad dream. They're stuck between sleep stages. Nightmares are very different. They are having a bad dream. They are experiencing something emotionally. They usually happen in the second half of the night when most dreams happen, during that time period. And with those, they will recognize the parent and be comforted by the parent coming in during the night and then talking about those things the next day.
