M.H.
My daughter was about the same age when we moved to a new house and she wouldn't stay in her bed. Finally on Dr's advice I did what he said and it worked! The first night you put him back to bed 1 time w/hug and kiss then sit outside his door and send him back to bed each time without opening door or having any more conversation. He will probably cry himself to sleep the first, second and third night but no matter how long it takes you have to stick to it. By the 4th night he'll stay in bed. You think the 4th night will never come but it does.
