My 2 year old daughter when she poos its dark green what should i do?

Poop Colors: The color of stool is not usually concerning, as it reflects a lot of things we eat. Dark black, red or white stools are the only colors that are worrisome.

Normal: The stool color is provided by the bile from the liver that is adds to fecal debris.It starts out a deep green & slowly changes thru greens to yellows to browns as the germs in the intestines metabolize the bile.Green generally means the stool in question moved through faster or was subject to less change by gut germs.
