The month at which an infant should be weaned from breastfeeding is related to the amount of breastmilk, the nutritional value of breastmilk and other factors, and cannot be generalized. In general, it is recommended to wean infants from breastfeeding at around two years of age. The World Health Organization advocates adherence to exclusive breastfeeding for six months and breastfeeding for more than two years. Generally within six months after delivery, breastmilk is of high nutritional value, rich in immune substances, trace elements, etc., which is conducive to infants obtaining nutrition through breastmilk. After six months, breastfeeding can be combined with complementary feeding. After two years of age, babies can be weaned off breast milk and fed with formula milk and complementary foods. It should be noted that if the amount of breastmilk is sufficient and the nutritional value is high, it is also possible to combine breastmilk and complementary feeding during the period from one to two years of age. In addition, breastfeeding mothers should pay attention to the diet, balanced nutrition, in order to prevent too little milk.
