constipation (tearing of the wall of the anus = blood)
if it's IN the poo....go to the Dr....could be something more sinister!
If it brown blood he needs to go to doc now!! as this maybe coming from his tummy and is not very good as might be internal bleeding but this is normaly accompanied by loss of appitite stomach pains ect so if he hasnt had that sort of stuff dont freak out
I have 3 boys!!!
