If we learn to observe the nature of the baby’s stool, and can distinguish between a variety of abnormal stool, you can generally understand what the baby’s digestive system problems: 1, the normal stool is: breast-fed babies, the color of the stool is golden yellow, soft and uniform fine paste, can have a small amount of fine particles of milk, sour odor, 3 to 6 times a day, slightly reduced after full-term; milk-fed babies, the stool is light yellow, drier If the stool has more milk flaps, it is due to undigested fat and calcium or magnesium soap; if the stool is scattered and unformed, we should consider whether the amount of complementary food is increased or the complementary food is not soft enough, which affects digestion and absorption. For artificially fed infants, if the stool is dark green and mucus-like, it means that the milk supply is insufficient and the infant is in a semi-starvation state, so additional rice soup, milk and milk substitutes must be fed. If the stool is very dry, add some vegetable puree or feed more vegetable water or fruit juice; if the infant eats green leafy vegetables, the stool may be a little green; if the infant eats tomatoes, the stool may be a little red. These are all normal metabolic reactions, and mom and dad don’t need to worry too much. When mucus, pus and blood appear in the stool, the number of stools increases, and the stool is as thin as water, it means that the baby may have enteritis, dysentery and other intestinal diseases, and needs to see a doctor in time. Once you suspect that your baby is suffering from a digestive disease, parents should not take it lightly and should keep a little bit of stool so that you can have timely laboratory tests during hospital visits and treat your baby for the disease in a timely manner according to the cause.
