E.T.
Hi, J.. We recently discovered that my 9 mo. old daughter has a milk allergy. She started with diarrhea, then mucusy stool. Later the diarrhea went away, but her stool was really dark, which means there's blood. She didn't spit up, though. If it continues, I'd go to the doctor right away. If the stool is dark, usually blood is present, which means that the intestines are raw. It's dark because it's old blood. I had to save some diapers to show the doctor when I went in for visits. We had to have blood tests run for food allergies and parasites. All were negative except a milk allergy. She's now on soy formula and doing well. Good luck!
