Night terrors help!

Hello! I think my 16m old has night terrors. The last 2 weeks she wakes up every night (sometimes 2x per night) just crying for no reasons. She seems really out of it (half asleep). Before we figured out what was wrong, we would take her out in the living room with us thinking she was just not tired. But it’s too consistent! The last couple nights we just soothe her and lay her back down.

Is there anything I can do to help her? She has a nightlight and sound machine. We do not have anything in the crib yet. I also checked into melatonin and most are 3years old or older. Anything I can give a baby? Could it be something else? She is healthy and no sickness. Doesn’t seem to be teething

Help!
