Hi Dr, I have a 1 month old baby. I started giving him Similac but changed to Nan Pro caused Similac milk makes him passing uncomfortably. His stool was hard. Nan Pro was better. His stool became yellowish and soft. I then changed it to Nan HA cos at tat time Nan Pro was out of stock. This causes his poo to be greenish in colour. And when he pass gas, it smells quite bad. Can I know what causes this change in his stool? What is the diff between Nan Pro and Nan HA?
