so, project big boy bed is not going so well. He refuses to sleep in it, and has taken to sleeping on the floor of his room. I have put the transition on hold for now, and since he is staying in his room (with 3-5 walk backs from me) will leave it a little while longer.
I actually lay in his bed this morning and he ran over and cuddled with me, so this might be my next approach. Lie with him for 5 minutes (as I do now, but in the bed) and then when I would normally leave, hope he stays there...)
