If a breastfeeding woman does not wean, sucking all the time will stimulate milk production and can produce milk for a long time. Breastfeeding enhances the bond between mother and child and also strengthens the child’s resistance. Because breast milk contains immune substances, breastfeeding, especially within 6 months after the start of breastfeeding, is very helpful in strengthening the child’s resistance. If we do not carry out weaning measures, allowing the child to keep sucking can stimulate milk production all the time. Since the early addition of complementary foods is helpful for the development of the child’s intestinal flora and taste buds, and breast milk is no longer sufficient for the child’s growth and development after the age of 1 year, it is recommended to start adding complementary foods to the child from about 4 months of age, and gradually reduce the amount of breast milk after 6 months of age, and complete weaning at about 1 year of age. During breastfeeding, women should wipe their nipples with a warm towel before each feeding to keep them clean and dry and to prevent the growth of bacteria. Remove the nipple from the child’s mouth in time after feeding, and do not let the child develop the habit of sleeping with the nipple.
