First of all, we should choose nutritious food suitable for young children to ensure a comprehensive, balanced and appropriate supply of various nutrients and calories. We should also pay attention to providing children with diversified foods to ensure that various nutrients can complement each other. Secondly, we should give full consideration to children's digestive ability and don't give them oily, coarse and hard food. When cooking, children's food should be chopped and cooked. Never give children fried and irritating food. Third, children's food should be distributed reasonably according to different seasons. Fourth, children's food should be carefully cooked, not only to avoid destroying nutrition, but also to suit children's tastes, and to increase children's appetite from color, smell and other aspects.
