A child can usually start adding complementary foods from around 6 months of age. Complementary foods can usually be added to a child’s diet from around 6 months of age. After a child reaches 6 months of age, the nutrients obtained from breast milk may not be able to fully meet the needs of growth and development. At this time, it is necessary to add some complementary foods to supplement the nutritional deficiencies, which will help the child grow healthily. Since the child’s digestive system is not yet fully developed, there are certain principles for adding complementary foods, which should follow the following points. 1. From less to more: At the beginning, you need to add more and more complementary foods, starting from a small amount and gradually increasing the amount, so that your child can adapt to the digestion and absorption of food. 2. From fine to coarse: You can gradually transition from pureed foods to minced foods. 3. From one to many: As the child grows older, the demand for nutrients increases, so it is necessary to add complementary foods from one to many in order to supply the child with nutrient intake. 4. From soft to hard: When your child first starts to add complementary foods, try to eat soft foods to avoid hard foods from hurting the mouth and digestive tract, or even foreign objects from getting stuck in the throat and causing breathing difficulties. If in the process of adding complementary foods, the child appears to refuse milk, anorexia and other situations, it is recommended to consult a doctor in time to the hospital for professional complementary foods.
