At present, the diet of young children aged 0-6 is mainly fed at home, and there are unreasonable factors in the feeding of young children due to the influence of traditional eating habits, life concept, food abundance and family culture level. It is important for parents to understand how to provide their children with a scientific, balanced and reasonable diet, and to carefully analyze and summarize the problems in feeding young children to improve their diet and nutrition during childhood and to ensure their growth, development and intellectual development. Here we introduce some of the different periods of children’s dietary arrangements and collocation. I. Newborn period At this time, because the child has just left the mother, gastrointestinal function is very weak, so the source of nutrition mainly relies on breast milk, breast milk is the best choice for infants in this period. Breast milk is the best choice for babies during this period because it is rich in nutrients, has the right ratio of sugar, fat and protein, is digestible and absorbable, and contains all kinds of immune substances that babies need to prevent various infectious and contagious diseases. In general, there is no need to add any food during this period. If there is no breast milk or the mother can not feed the child due to illness, should choose infant formula to feed the child, should not be fed with whole milk and so on. Second, the infant period refers to 0 to 12 months after the birth of the child, the growth and development of infants at this time is very fast, especially in the first six months, its weight can reach 2 to 3 times the birth, in addition to continue to breastfeeding, 4 months should gradually add supplementary food, such as batter, rice soup, vegetable soup, eggs, lean meat, soy milk, cookies, etc., to gradually weaning after 1 year old to lay a good foundation. At this time to add food should follow the following principles: from thin to thick, from less to more, from fine to coarse, from one to many, and in the child’s health, digestive function is normal when added. Third, the early childhood refers to children aged 1 to 3 years old, this period children’s physical development slowed down, but brain development accelerated, so the diet should pay attention to the supply of high-quality protein, at this time the child’s teeth have gradually come out, but chewing function is still poor, can not be with adults into the food, children’s food should be fine, soft, rotten, broken. The child’s food should be fine, soft, rotten and crushed. 250-500ml of milk or soy milk should be maintained daily, and attention should be paid to the supply of meat, eggs, fish, soy products, vegetables and fruits. Three regular meals plus one to two snacks daily. Note that at this time the child should increase outdoor activities, see more and more, like to eat a variety of drinks, small food, but small food to eat more will lead to anorexia, so the child should be controlled to eat snacks. At this time, children’s diet is close to the adult level, the main food can be ordinary rice, pasta, dishes with adults, but still avoid too hard, greasy or sour and spicy food. The diet should be diversified, meat and vegetables, alternating coarse and fine grains to ensure a balanced diet, and fruits should be added after meals, but drinks and snacks should also be used sparingly. During this period, children’s meals are basically the same as those of adults, but the dietary arrangements should be nutritionally adequate and the meals should be appropriate, paying attention to the following points: 1, food variety: that is, there are rice and flour, but also high-quality protein-rich beans, eggs, milk, meat, soybean, plus a large number of green leafy vegetables and fruits. Food should still have both coarse and fine grains, side dishes with meat and vegetables, to ensure that the basis of nutrition often change color to arouse the appetite of children. 2, three meals a bit most appropriate, because the child’s activity, consumption, breakfast is best to eat some milk, soy milk, meat and eggs. 3, to develop good eating habits, not partial food, less snacks, pay attention to dietary hygiene, do not read books, television when eating, focus on the idea of eating. We found in the clinical work of many children do not like to eat vegetables, for this situation, parents should start from education, so that children understand that eating vegetables can be supplemented with a variety of vitamins and minerals, very beneficial to their health, girls can be enlightened to eat more vegetables, red face, good skin, look beautiful; boys can talk about not picky food, partiality can grow taller. In short, no matter which age group of children, the diet should be balanced, to meat and vegetables, coarse and fine, and pay attention to the intake of high-quality protein, to develop good eating habits, not picky, not partial food, as little as possible to eat drinks, small food, so as to avoid the occurrence of obesity or malnutrition.
