Thanks so much girls. There really isnt anything more we can do to his room. We bought this house late last year and painted his room and did it all up. So its really nice and colourful with lots of toys. He also has a heater to keep him cosy. I think bottom line is that he is used to sleeping with us, so that feels right to him. I might take your advice and just sleep with him in his bed for a little while so that he gets comfortable in there. Fingers crossed for me!! Will let you know how it goes.
