M.J.
If He is the type that would get up and waunder around, I would leave him in the crib a little longer. A rule I always had with my kids and grandkids has worked great. Once they went to beds. I told them they had to call me before they got out of the bed. I told them I would be there if they needed me. But I did not want them to get out of the bed till they called my name out and I answered. I was abused as a child and it still frightens me, when someone taps me to wake me up. So it worked out great.
