My 3month old baby boy has been having green stools for more than a month. Occassionally it is yellow, but with green lumps interspersed.
He is formula fed(Enfamil Milk as well as Soy not at the same time) 2 times a day and breast-fed for the remaining.
The Pediatrician says that unless the stools have traces of red in them (blood) or black, not to worry.
Today it was light brown in color.
