My daughter is 3 years old and when she has a poo there is blood and she gets cramps. I been to the doctors and the is no change.
Go to a DIFFERENT DOCTOR! She sounds like she may be constipated. Try giving her prune juice (maybe with water to dilute the strong flavor), and make sure she's not spotting blood in her underware. She may be pushing so hard that she's got hemmorhoids and they're bleeding. A gentle child-friendly stool softener (at NEW doctor's approval) may also help. Also- does she drink a lot of milk and eat a lot of dairy? My best friend's son is five and if he has milk or other diary products he gets crampy and constipated. He's lactose intollerant. I've got the same issue. Just because she's a toddler, doesn't mean she cant have a lactose intollerance... maybe try that? (takes several days, even a week to clear up and actually notice a change)
my sister had that once when she was probably like 5 and shes 9 now and we went to the docter with her and she said it could have been somethingshe ate and it irritated her stomach or something. but I would also recomend loooking for another docter just to get more than one opinion sincethe docter you have now always says the same thing.
She may be constipated, which is causing hard bowel movements which in turn can cause hemorrhoids and fissures, which will result in bleeding.
Definitely get a second opinion...you don't mess around when you're child's health is at stake.
Take her to a different doctor then...and consider suing the first for mal practice.
Agreed with thedude, Get another doctor.
