the boy has diarrhea..

Ohh my the boy I'm taking care of is still having diarrhea until now and he has been suffering from it since Friday. He was home the whole day with me and just kept on crying coz he's always doing "kaka" and everytime he does it, he screams telling me "mal aqui" while pointing on his butt. And it means that his butt is already hurting which is very obvious coz his butt is already very red. I can really understand the boy coz I already experienced it, when my butt already hurts from defacating all the time, but I just can't control it to stop the excretion. And I'm really sad seeing the boy cry all the time. If I can only take his pain and make it mine, I'll really do it. But I can't, so all I can do is pray that he'll be okay tomorrow or the following day.
