If you are breastfeeding and the baby is otherwise well having green poo is not a problem.
It only becomes a concern when the baby?s weight gain is a problem. The number one symptom of a fore/hind milk imbalance is that the baby fails to thrive. This failure to thrive can be associated with green poo but not always and there are other reasons for green poo too.
The last mother I know who suddenly had green poo in her fully breastfed baby was because the mother started to take vitamin supplements. I?ve known other mothers whose babies often have green poos and are totally fine.
Green coloured stool in an otherwise healthy infant is not a cause for concern. But if you are worried it is worth a trip to the doctor.
Best wishes,
