Mini Codd is waking up in the night frightened. He dreams a lot and sometimes starts crying or calling in his sleep whilst he naps, and he looks terrified.
Having a Google (as you do), I was reading a post by a woman explaining similar and the doctor telling her it was 'nighttares' which are 'like nightmares, but the child looks awake but is still asleep'. After her posting a few times about 'nighttares' with some conviction, it suddenly dawned on me that the doctor must have said 'night terrors' to her, which she took away as 'nighttares... Like nightmares'.
