DS (3 and a half) just woke up screaming and crying very loud, DH went to him - I was in the bath. He kept shouting 'I want Mummy' so he brought him in to me and I cuddled and stroked his hair in our bed, talking to him calmly and reassuringly. He was very hot and sweaty and kept saying 'I want to go home'. I sent DH next door to borrow their thermometer and he went hysterical shouting 'I want Daddy'. He then said he didn't want me ( :( ) and has now gone for a bedtime story in his own room. He normally sleeps very well and he isn't ill at the moment. He was eventually able to answer questions and said he wasn't in any pain. We tried to give him some calpol but he went crazy.
I googled and it sounds like a night terror, but now I'm worried about what has caused it, and whether we're likely to get any more?
