Carbon monoxide is a poisonous gas and large amounts of it can be released from burning coal and by inhaling smokes from cigarettes. Babies take in oxygen through the placenta for their growth and development. When a pregnant woman inhales carbon monoxide and other harmful gases, these gases replace oxygen in the baby's bloodstream, reduces the amount of oxygen that is used by the baby.
