<s>[INST] Hi Doc, My son is 02 years old and for couple of days his poo color has changed. After normal poo he is again going poo is very small quantity with greenish color and sticky. Though this is happening 02 to 03 times in a day. He is eating good and is having both cow milk and mother s milk. [/INST] I am glad that you have put up your query at Chat Doctor. I understand your cause of concern. But I would like to reassure you since greenish stools are often normal. Greenish stools may occur when food might be moving through the large intestine too quickly, such as due to diarrhea. As a result, bile doesn't have time to break down completely. Green stool can also be caused by taking iron supplements or eating certain foods such as green leafy vegetables, green food coloring, such as in flavored Chat Doctor.  Foods with dark purple coloring, such as Kool-Aid, popsicles, and gelatin (Jell-O), can also result in greenish or green stools. In case you wish to be even more certain, I insist that you consult a pediatrician. </s>
