I know exactly what you are going through. My daughter was the same way since birth. She had so many tests done and seen so many doctors. It turns out that she is VERY lactose intolerant! Once I switched her to lacto free milk and they make a lacto free chocalote milk...watched what she ate....now she is doin great!!!!!Her stools are normal and now she doesn't SCREAM while trying to move her bowels. It was so bad when she was little that she would hide in a corner and cry and scream till she was done she was so sweaty from straining I would just sit and cry. Ask your doctor if maybe this could be a possibility...Good Luck and I hope everything turns out well. Shelly
