My ds who is 3.8 has been having what I think are night terrors for a while. He is usually asleep between 7.45 and 8pm and then at around 10.30/11.30pm will sometimes scream/sob (heartbreakingly so, not like normal crying, this is real heart-wrenching sobbing. Sometimes it's enough to just go in and stroke his face and reassure and then he's fine for the rest of the night. I know if it's a night terror you're not supposed to wake them up. All the stuff I've read about night terrors seems to say that it's just one incident per night. However, some nights it seems to go on throughout the night at intervals. He never seems to remember anything the next day. Then this morning he said that he had been having dreams last night and I asked him if he remembered waking up and he said he did, which is different from the other times. It doesn't happen every night and we had a few weeks recently where he was sleeping really soundly, however this week it's started up again. He is a happy boy and there isn't anything stressful going on at home. It's just horrible when it happens and we feel powerless. Does anyone have any advice?
