My son was the same way, I tried sleeping with him at first and he would wake up and look for me. So now he goes to bed everyday at 8:30 and he has his fav pillows and blanket, we put on the night light and close the door. He used to cry for 10-15 minute but that stopped after a week. We really tried to do the same thing every night and get him into the bed before he was too tired. It was hard but now he sleeps good in his bed and loves it.
