thanks ladies, he seems to be ok with everything else. he is passing bowel movements twice a day, lots of wet nappies, good energy when he is awak etc though if anything is sleeping more. and now I feel even worse in that I totally didnt think to consider that when he was 4 months old we found out his left kidney doesnt fully function (but only by 5%) I have no idea why it didnt come to mind. it was such a gradual change, but its noticeable now.

13health just said to see the Dr in the morning. Will call his paed instead I think, I googled, shouldnt have done that.
