S.S.
My now 3 year old daughter did the same thing at that age and it was horrible. My peditrician told me that if it is happening around the same time every night it is terrors. She suggested we went and wake her up 15 min before it normally happened then put her back to bed. We did this for 3 nights and it stopped it. It breaks there sleep pattern so they don't have them. It was very rough though because it was hard to get her back to sleep after she was woken up but in the end it was worth it. I have another daugther who is 14 months and I am praying we don't go through the same thing with her. But I wouldn't be so concerned about the title night terrors as long as you get them to go away. Night terrors, night mares they are both bad and it's a phase. Hope this helps
