Well its a new day, and he actually slept through the night, which i am amazed about.
I am now hoping his appetite returns, as he has barely eaten in days, he will snack here and there, and he is not normally a big eater anyway, so he is having less than he usually does.
He would not drink his formula, and with only 2 weeks or so to go till he turns 1, we swaped him to full cream cows milk, which he seams to be drinking.

He worries me when he coughs, it sounds so bad.
He has been such a trouper, still smiling, and so happy, even when he is crying, he will manage a smile.
