And refuses to go back to sleep, what do you do? CIO? Get them up to play? Something else? I have tried earlier bedtimes and later. Neither have an effect. I have tried leaving him in the crib. He screeches and screams until we come and get him. He is not fully rested at 4:30, but wants nothing to do with being held or rocked. He is getting 4 molars right now, but when he is playing he is perfectly content so I dont think it is pain. We try not to do breakfast until 6 so he doesnt get used to eating that early, and then he goes down for a nap right after because he is so tired. This has been going on for almost 6 weeks. HELP!!
