Breastmilk is the natural food that satisfies the physical and psychological development of infants, and it is usually appropriate to wean infants from about 8 months to 1 year of age. Breast milk has an irreplaceable role in the healthy growth and development of small infants, so when to wean breast milk has a great impact on the development of the child. Generally within 6 months, you want to provide your child with sufficient breastfeeding because in mother’s breast milk, the nutritional value is high and easily absorbed and utilized by the child, its nutritional ratio, especially the ratio of essential amino acids is very suitable, other nutrients are also easily absorbed by the child, and at the same time breastfed babies rarely have allergies. Not only is it rich in nutrients, but it also has biologically active substances that help the child’s healthy development and are not replaced by other milk powders. As children get older, they gradually start to add complementary foods after 6 months, and breast milk will not be the only source of food. At the same time, the mother may have to go to work and work at this time, so the feeding time cannot be guaranteed. It is recommended to gradually replace breast milk with formula when weaning, and it is better to wean the child when the child is healthy and the weather is not too hot.
