Weaning generally refers to weaning from breast milk, formula and milk can be consumed for life, formula when young, and fresh milk after 2-3 years old. The ideal time to wean a child from breast milk is when the child is 2 years old. After the age of 2, the child is basically meal-based and can be supplemented with fresh milk or formula milk as appropriate. Weaning is usually done when the mother goes to work at the age of 2, so it is easy to wean the child during the day, and when the child cries at night, the mother tries not to feed the child again, so that natural weaning can be achieved. However, some children have more difficulty, and there is usually a 1-2 week period of difficulty for the child to adapt. If the mother needs to wean, it will be harder for both the child and the mother, and the child will not adapt as well, and some mothers will have to take breastfeeding pills if necessary.
