My daughter had night terrors about the same age. She would cry & gag like she wanted to throw up. She would have no memory of them the next day. She often had them the same day she had attended a birthday party which made me suspect she was sensitive to either all the sugar, red dye or 'too much' excitement. I made an effort to avoid any snacks,juices or drinks that contained dyes or high fructose corn syrup. She 'outgrew' these episodes the same year.
