The main characteristics of children's diet are: from infancy to milk, supplemented by food, to food, supplemented by milk. The cooking methods and food used in meals are more and more close to ordinary family meals. However, this change should adapt to the gradual improvement of children's digestive and metabolic functions, and should not be rushed, so as not to cause digestive and absorption disorders.

Children's diet must have enough heat and various nutrients. There should be a balanced relationship between various nutrients. The supply ratio of protein, fat and carbohydrate is 1: 1.2: 4, which cannot be unbalanced. If the child is only given rice porridge or white rice and pickled vegetable soup after weaning, the fat supply in protein is insufficient, the growth and development are slow, and the disease resistance is low; If we only pay attention to providing children with high-protein foods such as eggs, milk and meat, the supply of carbohydrates is insufficient and the energy demand is often not guaranteed. Some children seldom eat vegetables and fruits, which will lead to the lack of minerals and vitamins such as calcium and iron. In short, after the child is weaned, the dietary composition should be sufficient, high-quality, diverse and nutritious on the premise of taking care of digestion.
