My 4.5 month old baby sleeps on his tumy every night, which I am OK with. The problem is that he will rollover during the middle of the night to his back and can't rollover and cries until I wake up, nurse him and turn him back over, about every 3 hours. I am trying to get to the point where I don't have to wake up every 3 hours and just sleep though the night. Also when I put him down to sleep, he fusses and cries and will rollover many time before he goes to sleep, but he can't sleep on his back. Help I don't know what to do.
