Generally, babies over 4 months old can add complementary food, from less to more. It is ok to eat a little, but don't eat too much. Yogurt-dissolved beans should be eaten after the baby is 2 years old, and 0-/kloc-0-year-old baby should mainly use breast milk or formula milk. Baby-dissolved beans can be used for a long time during the baby's growth. However, the most important thing for a baby is not to have a partial eclipse. The diet should be as wide and diverse as possible. Eat more high-quality protein foods, eat more fresh vegetables or fruits, and add appetizing snacks in moderation. When making complementary food for the baby, it is best to eat and cook it now. The utensils added with complementary food should be disinfected frequently to prevent the virus from invading the baby.
