My baby has had light green poop for a week. doctor says its a tummy bug but im really worried. baby is unsettled sometimes but happy most of the time?

Green is normal: The body adds bile to the digestive process that colors the poo.It starts out dark green & gradually changes through green, yellow & brown as agents make metabolic changes to the bile.Green is a normal stool color that can infer things are moving through quickly.

Green poop: If your baby is happy most of the time and is eating and drinking well, don't worry. Perhaps the green poop is probably caused by foods he's been eating.
