After the baby is 4-6 months old, we recommend adding complementary foods. After the complementary foods are added, parents must pay attention to the baby’s whole body reaction, such as whether there is vomiting, whether there is a rash, in addition to observing the nature of the stool. Generally speaking, if the baby eats rice flour, the stool should be yellow, striped soft stool. If the baby eats rice flour after the bowel movements are the following conditions, you should pay attention to the need to adjust the intake of complementary foods. If the stool is thin paste or thin watery stool, if the baby’s stool is hard and pellet-like, or is more difficult to defecate, these are some abnormal situations. It is necessary to adjust the addition of complementary foods, or continue to observe the stool during the process of addition.
