At Home with the O

You may say, "oh a crying baby, that's totally normal." The difference is that this baby is still sleeping while screaming. At first, we thought it was gas because it was accompanied by some manly baby farts. But, the last few mornings there have been no toots. Then, we thought he may be starting to teethe because we had a terrible day yesterday that involved crying, drooling, chewing, and a possible low fever. But, there are no bumps on his gums. Finally, we thought that he may just be hungry because the only thing that would soothe him was his pacifier. But, when I wake him to feed him he eats a little and then falls asleep and the screeches begin again.

Ultimately, we have no idea why he is doing this. Any ideas?
