If your baby is happy in daily life, in good spirits, growth and development, appetite and other aspects are normal, but only occasionally green stool, parents do not need to worry too much. Because the baby green stool is a normal physiological phenomenon, usually due to dietary factors, as long as the diet is adjusted, the baby’s green stool will soon return to normal. If the baby did not eat enough, hunger makes the intestinal peristalsis too fast, will not have time to fully digest and absorb the nutrients, with a large amount of intestinal fluid plus bile and stool together with the discharge caused by green stool. If the baby is in this state for a long time, it will cause chronic malnutrition in the baby, and in the long run, it will eventually lead to delayed growth and development of the baby, including backward physical development, backward motor development, backward language development, and backward intellectual development. The more frequent the baby’s green stools, the worse the baby’s physical condition. The baby’s nutrition can not keep up with the needs of the baby will also lead to the baby’s immune system decline, prone to infectious diseases. Severe cases can affect the baby’s life. Therefore, parents should ensure that the baby’s diet when caring for the baby, do not let the baby appear hungry or too full, nutrition should be balanced, avoid eating some raw and cold, difficult to digest food, avoid abdominal cold. If your baby has green poop for a long time, go to the hospital to find out the cause and make the right treatment.
