My 2 yr old son has recently taken to screaming at night. He always wakes up between 12-4 in the morning. Sometimes once, sometimes multiple times. And sometimes he'll even stay up for 2-3 hours crying, moaning and screaming. I know some nights it's night terrors but the screams are usually different and for different lengths of time. I'm not sure what to do for him. We have some speech delay so he can't tell me what's wrong. He's clearly not sleeping and neither am I. Has anyone else run into this problem?
