To increase children's appetite, we should pay attention to the following points: First, don't add snacks and drinks to your baby between meals. Second, pay attention to the matching of color and appearance when eating, and you can change interesting tableware to make your baby interested in food. Third, we should establish a good dining atmosphere when eating. Adults and children should eat together. Don't turn on the TV and mobile phone when eating, and don't eat for more than 20 minutes. Fourth, if you still have poor appetite after the above improvements, you need to go to the hospital to rule out the possibility of pathological diseases, such as enteritis and spleen-stomach disharmony, and if necessary, you should be treated with Chinese medicine massage or medication.
