It is generally appropriate to wean babies from nighttime breastfeeding when they are about 4 months old, but it also depends on the specific situation. Night feeding refers to breastfeeding at night, and the demand for night feeding is also very strong in the first four months of the baby’s life, and night feeding can also promote lactogen secretion and increase the amount of milk continuously. However, after the baby is four months old and can sleep for several hours at night without any signs of nighttime nursing, there is no need to wake up the baby to nurse, and the habit of nighttime nursing can be gradually eliminated at this time. If the breasts are not swollen at night, the mother can sleep peacefully, but if the breasts are particularly swollen, you need to express some milk to ensure that the milk continues to be secreted. Generally, after 6 months of exclusive breastfeeding, you can add appropriate complementary foods to your baby gradually under the guidance of your doctor, which is conducive to your baby’s growth and development.
