Update on not sleeping

Josiah is still having difficulty getting to sleep and staying asleep. I feel like we are dealing with a newborn. Last night it was almost 11:00pm before he finally crashed, but Dan said that he was up screaming histarically by 1:00am (he had turned the monitor down and forgot to tell me, so I never heard that). Dan ended up sleeping in his room until 4:00am. And then again at 6:00am he was screaming again. Crazy types of screams, ones that make you want to run right in and see what's wrong. So he could be playing us, but at this point how long do you let a kid scream. It was 3 hours last night on and off. Unfortunately we made the choice to bring him into bed with us and he never went back to sleep, except for a 15 minutes snooze there sometime before 8am. Oh well! Hopefully tonight will be better. We have no idea what is going on! Could be nightmares, his mouth could hurt, he could have a cold and ear infection and he could simply be playing his mom and dad, pushing his limits. Kids are so hard to read at this age. We are stumped.
