I was wondering if anyone could give me some help on how to help my son poo. He was constipated 2wks ago then finally done a really big poo but it hurt his bum, so then he went to trying his hardest to hold it in. He finally pooed and was fine for a few days but now hes doing it again! He has nappy rash on his bum now cos he had diarrheoa(sp?) and he wont poo cos its hurting his bum again? Hes 2 and a half any help is much appreciated. He goes to c the doctor tomorrow but i really hate seeing him in pain =(
