A. Hello Parents, Green Baby Poop: Babies taking an iron-supplement will often have green baby poop. Green baby poop can also occur at 4 to 6 months when they start eating solid, green foods, such as pureed peas, spinach and beans. Orange, Yellow and Brown Stools: These colors are normal in breastfed and bottle fed babies.
