the important thing is that if the consistency of the stool is either watery or it is either very hard then only you have to visit the doctor. when the growth of the child is proper and the child is not having any other complaints and stool consistency is semi solid to solid then do not worry about the frequency, colour as well as the smell of the stool. the green colour that many times is present in the stool is due to the digestive enzymes (bile )present in the stomach and when the food reacts with the digestive enzymes this can give green colour to the stool. the importance is of consistency of the stool so if the consistency is watery and green then only you need to meet the doctor but if it is semi solid to solid green stool then no need to meet the doctor.

When the baby is on formula milk , the stool consistency and color can vary a lot , so do not worry about it until you feel the baby is unwell
