My 18 mo DS has no problem going to sleep, in fact he asks for his bottle of milk and takes himself upstairs, the problem i have is keeping him asleep. For the last 4 weeks he has woken everynite between 0130 and 0230 and screams the place down until i go into him. He quietens down until i leave the room again. Last nite i was so tired i felt like i was in control of myself and that really scared me. Anyone got any ideas of what i can do.
