Hi, my 13 month old son has suddenly started crying/screaming at night. When I go to him, he is still asleep and it is very difficult to comfort him. Sometimes, I manage to wake him up and he eventually calms down, other times I can't wake him, but somehow manage to calm him down. Occasionally, he will open his eyes and I think he is awake, but I realise he is still asleep. Do babies get night terrors? Has anyone else experienced anything like this? Thanks
