Our two yr old decided 3 weeks ago that she no longer wanted to sleep in the cot, she wanted to sleep in the big bed. So we moved her. Since then, she will not go to sleep unless we are in the room with her. It doesn't take long intially, but she will wake during the night (up to 4 times) and will not got back to sleep unless one of us is in the room with her....otherwise she will SCREAM and climb out of bed. Prior to this she was an excellent sleeper. It had been suggested to put her back in the cot, so we did and what a disaster. We need help as we don't want to let this continue much longer as we are exhausted (both working full time) and she neeeds to sleep through.
