Think DS1 (20 mths) had a night terror last night, started screaming / crying unconsolably at about 9.15pm. Could not comfort him, the normal shushing / patting did nothing, he kept on crying, didn't want to be picked up, kept saying "no". But he didn't want to be in his bed either. Wasn't sure if he was really awake or not. He stopped eventually as I cuddled him, then he appeared to be asleep instantly.
Not sure if this was a NT or not, or if not what else it was, he has never been like that before at night.
