Ds2 (3) has had diarrhea for 5 days now and although he is toilet trained i have had to put him back into nappies as he poos so much! i took him to the dr yesterday who said i have to get a sample (lovely) and send it to the lab at the hospital, but today, well just now he has gone on his potty and its got blood in it - not loads but quite a bit - should i be worried what do you think i should do? he seems ok in himself and has been running about and playing, but im sure its not ok to have blood in your poo!??
