Pay attention to the following aspects when cooking chicken soup for a one-and-a-half-year-old baby: First, the cooking time should be longer, at least three hours, to ensure that it is cooked and boiled, which is easy for the baby to absorb. Second, blanch with boiling water before cooking to remove blood. Remove fat in the process of cooking chicken soup, and avoid being too greasy to avoid diarrhea symptoms after eating. Third, don't let go of too much seasoning when cooking, especially put less salt. You can put a little green vegetables, such as a small amount of parsley and cucumber, to keep the soup delicious and stimulate your baby's appetite.
