Dark Green Stool with very foul smell

Mommies baka lang po may naka experience sa inyo na nag poops si Baby ng Dark Green (Mushy)? Ang Gatas niya po ay Nan Infinipro HA (One). As per Pedia niya normal variant naman daw po ito pero sobrang maamoy po kasi poops niya. Please share your experience po if any. Maraming salamat po in Advance.
