## **Core Concept**
The passage of greenish stools, also known as bilious stools, in a newborn can be a sign of various conditions. In a 3-4 day old newborn passing greenish stools 8-10 times a day, it's essential to differentiate between physiological and pathological causes.

## **Why the Correct Answer is Right**
The correct approach involves understanding that greenish stools in a newborn can be a normal occurrence, especially if the baby is breastfed, as breast milk can cause stools to be greenish or yellowish. However, frequent passage of greenish stools could indicate an issue such as infection, allergy, or obstruction. The management often involves monitoring, ensuring proper hydration, and sometimes adjusting the feeding.

However, bilious vomiting or stools in a newborn should prompt an urgent evaluation for surgical causes like intestinal obstruction.
