By chance, the day before yesterday, I heard an old expert in the maternal and child health care system (it is a bit old) talking about the need to feed water once a day after the baby is born. This view is not correct. With regard to infant feeding, in recent years, many important concepts have been updated. Many textbooks about baby feeding in the 1980s and 1990s are “outdated”. Feeding babies is one of them. There is also a typical outdated saying "add supplementary foods starting in 4 months".

　　According to the Global Strategy for Infant and Young Child Feeding published by the World Health Organization (WHO) and the United Nations Children’s Fund (UNICEF) in 2002 (such as the title map, download the website of the CDC of the Ministry of Health), in order to achieve the best For growth, development, and health, babies should be fully breastfed during the first 6 months of life, that is, only breast milk. The document emphasizes that “total breastfeeding” means not feeding any food or drink other than breast milk or even water. However, infants are allowed to take drops and syrups (vitamins, minerals and medicines).

　　It can be seen that babies start feeding supplementary foods at 4 months of age, rice porridge, fruits and vegetables are actually inappropriate (of course, considering that some babies are born with a large birth weight and supplementary foods such as special rice noodles) , Egg yolk and other nutritional qualities are high, "Chinese Resident''s Dietary Guidelines 2007" uses a vague statement-babies add supplementary food from 4 to 6 months). Some mothers start to give supplementary food when their children are 3 months old, eager to achieve success, not gaining more than gain. WHO recommends that babies begin to receive complementary foods other than breast milk when they are 6 months old (180 days).

　　According to the recommendations of this document, complementary foods should be fed 2-3 times a day during 6-8 months, and increased to 3 times a day during 9-11 months with a nutritious meal. During the period of 12 to 24 months, three meals should be given, and two additional nutritional meals (three meals at two points) can be eaten at will between meals. Moreover, all food should be healthy, safe, and nutritious. Feeding infants and young children requires active care and motivation to encourage children to eat.

　　The document recommends that when supplementary foods are added, breast milk should be fed frequently (an unlimited number of times) and continue to be fed until the age of 2 or above. Unrestricted breastfeeding will make milk secretion more abundant.

　　Like medical science or any other discipline, nutrition is also constantly evolving, new research, new evidence, and new ideas are emerging, and old knowledge, ideas, and therapies are being eliminated. As professionals engaged in nutrition-related work, we should pay close attention to the latest developments in this discipline, at least to understand those critical changes. Using the outdated theories of the 1980s to guide the practice of the 21st century, what expert is that?
