My 3 year old son shouts in his sleep, probably 2 nights in 3. It starts as dreaming but can wake himself and carry on shouting. I've read to stop shouting I shouldn't give him attention. But he shares a room with his sister and we live in a small flat so he wakes everyone. I end up co sleeping as it calms him and gives everyone some sleep. He doesnt generally need anything and it starts as dreaming. Any one got any advice ?
