Late weaning is very harmful to children. As the child grows up, the nutrients in breast milk can no longer meet the child’s growth needs. If the child is not weaned in time, the child will not be able to keep up with the nutrition, which will cause the child to be thin, malnourished and sickly. The later the baby is weaned, the more dependent he or she will be on the mother, and the more likely he or she will lack a sense of independence and develop a withdrawn and uncooperative personality. Therefore, it is important to choose the right weaning time according to the baby’s physical condition.
