Ice consumption has been linked to premature birth and low birth weight in unborn babies. When pregnant women consume ice, it can lead to a decrease in the body's temperature which affects the baby's development. Studies have also shown that ice consumption during pregnancy is associated with an increased risk of having a small for gestational age infant or preterm delivery. As well, consuming too much ice while pregnant can result in dehydration which may affect the supply of oxygen and other nutrients needed by both mother and baby. Ultimately, if you are pregnant it is best to avoid eating large amounts of ice as this could potentially put your unborn child at risk.
