Cause and Effect

Ryan has learned a new trick - he can roll over from his back to his stomach. The problem? He hates being on his stomach. And he insists on rolling over EVERY time he's on his back. This includes in the middle of night, when he wakes up. He used to soothe himself back to sleep with his thumb - but now he rolls over and then cries until we flip him back. I guess this is one of those of 2 steps forward, 1 step back kind of things right?
