At present, there is no particularly strict requirement as to how many months a baby should be weaned from breastfeeding, and if possible, it can be fed until about 2 years of age. Breastmilk is the best natural food source for babies, providing all the nutrients for babies, especially babies under 6 months old, so babies under 6 months old should be exclusively breastfed as much as possible. After 6 months, you can continue breastfeeding until 2 years old if possible. Because different babies have individual differences, the weaning time is also different, and there is no specific requirement on how old the baby should be weaned. If there is insufficient or no breastfeeding during the breastfeeding period, a certain amount of formula milk will be given under the guidance of the doctor. At the same time, complementary foods can be added after 6 months, so that the baby will also wean naturally after adapting to eating complementary foods. It is recommended to pay attention to provide sufficient nutrition to the baby, so as to promote the normal growth and development of the baby.
