Sleep? What's that

So, I'm not sure what has been going on with Riley lately, but we've had huge sleep issues. His doctor thinks they're night terrors (a little different from nightmares), and gave me some information about them which basically says they'll outgrow it sometime by age 12 (if we survive that long).

I'm starting to wonder though, could it be just another symptom of the terrible 2's?? He's been basically having temper tantrums in his sleep. He screams "no" over and over, and "I can't do it". He screams about his bebo (belly button) and kicks the blanket off then screams for the blanket to be put back on.

I'm so torn as to what to do. This has been going on for about a month or so, and I'm just not sure if he needs sleep training, or if it has something to do with the cold he had (now pneumonia), or if he is having these night terrors. I just feel so lost. We were up from 11:30 until after 2 am last night, and I'm just exhausted. It's also really hard to keep calm when you're 7 months pregnant, dead tired, and listening to screaming for over 2 hours!! I am starting to crack a little, and I'm not sure how I'm going to handle this with a newborn!
