The past few days D has been waking up and full on shrieking. He's 5 months and used to go much longer between wake ups and now he's up every 2 hours, practically like clockwork. There's no letting him fuss it out, as he's screaming bloody murder almost immediately.

Last night he woke up 1.5 hours after a previous waking and I told DH to get him, that he didn't need to be fed. D screamed and screamed while DH shushed and rocked him and tried to give him the pacifier. After a few minutes I said I'd just feed him and then he kind of passed out when DH put him next to me in bed. Other times he's done basically the same thing, but only calms down when he's fed. I know he can go much longer than 1.5/2 hours between feeds. He just get so worked up and nursing calms him.

Is this normal? His sleep has been so bad I'd like to start considering sleep training, but now that he's not just crying he's screaming I'm starting to wonder if something's wrong. He has been sick, but it seems like it's starting to clear up a bit.
