There is no uniform time concept for the hardest days of weaning, and it needs to be judged according to the patient’s individual situation. Weaning usually takes about 7-10 days, but some children are more dependent on their mothers, so if they are weaned too quickly, it may cause harm to the child’s psychology, so you can slow down the speed of weaning and progress gradually. The timing of weaning depends on the child’s emotional and psycho-physical condition, and whether the mother is adequately prepared. Generally advocate breastfeeding until about one year of age, the child at 4-6 months can add complementary foods to supplement the nutritional needs, but also to prepare for weaning, and then increase complementary foods, and gradually reduce the number of breastfeeding and breastfeeding amount. Do not suddenly wean off breast milk, so that the child does not adapt to other foods, diet reduction, and even affect the child’s nutritional development. Scientific research has proved that breastfeeding can enhance the relationship between the mother and the child, but also let the child form a kind of dependence on the mother, if suddenly weaned, will cause psychological harm to the child. If there are various reasons why the mother can not breastfeeding, must be weaned gradually increase the amount of formula milk, until the child gradually adapt to the slow weaning of breast milk. Baby weaning should pay attention to the time can not be too early, generally more than 6 months before weaning, it is recommended to wean the child in the spring and fall, the weather is too cold or too hot, the child is easy to not be able to adapt to the temperature and lead to a decline in immunity, resulting in colds and fevers and other symptoms.
