I'm nver sure about this. I want him to have fluids, but if he's just going to be sick again maybe he's better off with nothing for a bit.
He has been sick about 8 times today (just yellow bile now). Bizarrely he seems fine in all other respects. He had what appeared to be a very mild bout of chicken pox last week. All spots have scabbed over and almost gone already, but could the two be related?
