Why would a 2 year old girl have creamy white colored stool with light greenish tinge?

It could be an indication of

* Liver infections, such as hepatitis * Biliary cirrhosis * Gallstones * Anatomic abnormalities of the intestines or bile ducts present at birth (congenital) * Inborn errors of metabolism * Sclerosing cholangitis * Narrowing (strictures) of bile ducts * Cysts * Tumors * A side effect of certain medications, such as some antibiotics, antifungal drugs and antacids I suggest contacting a doctor if it doesn't return to normal color in one day or if the child becomes visibly ill.
