Hey moms..

My almost 9 mo old baby has now been sleeping in his own room in his crib at about 5 months old now. My baby was a fairly good sleeper, but lately the past 3 nights he has been waking up screaming at 3am. When I go into comfort him, it appears that his eyes are still closed and he will not stop screaming until I put his tv show on. I been sitting with him on the couch for about 15 mins with his show on until he settles down. At this time he seems tense and his body is shaking. What could this be?? Is it nightmares?? I thought separation anxiety would be if I picked him up, he would stop crying, but that is not the case. After changing his diaper and him refusing a bottle, he still screams until we make it to the couch and his tv show goes on. Should I be concerned? Has this happened to any other mamas?
