Uy, green poop is actually normal sa Gentlease kaya don't worry! A few of us here use it din, and lahat ng babies namin may greenish tint lalo na kapag newly introduced pa lang ang formula, it usually settles after a week or two once their tummies adjust. Pero if it's paired with diarrhea, mucus, or your baby seems uncomfortable, check with your pedia na lang to be safe, okay?
