Good day, My baby is 11 months old and suddenly his stools color changed to a very pale yellow. It has been this way for a week.

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.Yellow generally means the stool in question moved through faster or was subject to less change by gut germs.Normal color reflects return to normal feeding activity.
