Bless him, I have no idea when he was sick, it was all up on end of the cot and he had slept in it all night. Hence having red patches all over his face where I assume it has chafed or burnt it.
My first thought was he could have choked and I would never have know. That absolutely terrifies me and I can't stop cuddling and kissing him. I am a light sleeper and would have woken if he'd cried out. Poor little boy 
I think he over-ate last night and his tummy couldn't cope with the amount of food at that time of night, so it was our fault. It could be a bug but he seems absolutely fine, no poo in his pants. A child in his crèche was sick in the week but all the other children were herded up the other end so I don't think they came in contact with anything directly. Also it was early in the week, so if he was going to catch something wouldn't it have happened earlier?
As I said I think it was too much food at 7.30 ish and his stomach just thought better out than in and got rid of it.
God I feel like a piece of shit. If something had happened to him in the night my life would effectively be over, he is everything to me
