Hi, this is Sangeetha Kannaiyan from Chennai, I have recently delivered baby 4 months back ok December 2017. Now he has complete freedom 4 months and stepped into 5th month. Am feeding breastmilk to him since he born. No formula anything else. Since yesterday he is getting green stools and he was good and normal like usual, no changes in his behaviour like any physical illness. Please assist is this any serious issue or a normal one.
