Okay, before I give you the low down, let me just note that I live in Northern Ireland. This means that I don't have NHS Direct or Urgent Care Clinics. Let me also note that my son has already seen a GP, this past Thursday.
So the problem is that he has had diarrhoea for the last 8 days. As I said, he saw the GP on Thursday, or day 5 of it, and was told there was nothing they could do so long as he's not dehydrated, which he is not. He is eating fine and drinking loads.
But whether he eats normally or the BRAT diet it just goes through him and comes out mostly liquid with bits of solid. Poor boy is 2.4 and still in nappies and his bottom is just raw!
So, after being told there was nothing to and "better out than in" would you try to get him to a GP tomorrow?
