This is a happy monkey!!! We gave him a "big boy pillow" tonite before he went to bed.. He hasn't moved in over an hour.... Straight to sleep, arms behind his head!!! So far he hasn't had a problem with the big boy bed... This morning he didn't get up til I came and got him after he yelled for me and at nap time he woke up and calmly hot out of bed and started playing in his room... So we shall see
