Goodluck mate, I hate those nights with the unknown. I have been known to sneak a mattress in the girls room when one of them is sick to sleep on... I don't sleep well, but probably better than if I was in another room.

I would go in and feel him and see what you think, remember that when they sleep they warm up anyway.

ETA: posting at same time, good news!!!! YAY! I would go to bed then
