77-day baby development standard

In fact, the development of babies at 77 days old is not that obvious. You will just feel that their weight is heavier than when they were born, and you will also feel that their height is increasing, but it is not yet in the golden period of development and growth. At this time, parents should pay attention to conditioning the baby's body and must pay attention to a balanced nutrition so that their baby's development can meet the standards.

Nutrition is the material basis for ensuring the normal growth, development, and physical and mental health of children. Children's need for nutrients is higher than that of adults. This is because two requirements must be met, namely, the needs of growth and development and activity. Infants and young children in particular grow and develop most rapidly, requiring large amounts of protein and other nutrients, so this must be given attention.

After weaning, children need to have a balanced diet and eat as many different foods as possible to ensure the need for energy and nutrients and maintain a balance between nutrients, so as to avoid malnutrition due to nutrient deficiency or obesity due to overnutrition, which will affect the normal growth of children. Therefore, it is very important to cultivate good eating habits in children from an early age and not to be picky eaters or eat snacks randomly.

In addition to maintaining a good appetite for children, they should also develop a regular life, get enough sleep, and regularly participate in outdoor activities. This will help prevent disease, promote digestion and absorption of nutrients, and enable children to grow up healthily.

Effects of trace element selenium on children's growth and development

my country is a country with selenium deficiency, with 72% of its regions being selenium-deficient. Selenium is an essential trace element for the human body and is absolutely indispensable. Especially the special group of children, who are in a critical period of growth and development, have a relatively strong demand for the trace element selenium. Once the trace element selenium is deficient, it will have irreversible effects on children's growth and development.
