can't sleep

Neither I nor Tate can sleep. He is seriously having trouble breathing and it is freaking me out. He can only breath if he's upright and on his tummy. He did okay sleeping from 8:25 until about 10:45 and then he must have gotten on his back because he started crying a panicky cry...not his usual cry. I went in there (which I never do) and he was half asleep, but couldn't get his breath until I sat him up and it's like it just opened up his airways and he could get a deep breath. So I just held him that way for a bit and I just layed him back down on his tummy and stuffed a big blanket under his crib where his head is so that he's more upright. He does okay, but then he has a moment when he can't get a breath and when he finally does, he starts to cry. I have a feeling the next couple of nights are going to be long ones. I am so paranoid, I don't know how I am going to sleep tonight. I wish I had taken tomorrow off work too because I am going to be tired tomorrow! Please say a prayer for my baby...we would appreciate it!
