There are two kinds of mixed feeding methods for infants: “Complementary feeding method” and “substitute feeding method”, the complementary feeding method is for infants within 6 months and the substitute feeding method is for infants after 6 months. 1. Complementary feeding method: it is suitable for infants with insufficient breastmilk within 6 months, and at this time, only formula milk can be added for mixed feeding, when there is breastmilk, breastfeeding can be carried out, and the insufficient part can be made up with formula milk. If operated properly, it can effectively promote milk secretion, and it is possible to realize complete breastfeeding. 2. Substitute method: applicable to the amount of breastmilk is sufficient, but due to the breastmilk mother something can not give the baby breastfeeding on time, can only be applied to dairy products or milk substitutes instead of once or several times of breastfeeding. 6 months after the baby has been added to the complementary foods, such as breastmilk is insufficient, can be used to supplement the complementary foods or instead of 1 to 2 times of breastfeeding, to ensure that the baby’s nutritional needs. If breastmilk is sufficient mixed feeding applies to infants after 6 months, at this time you can gradually add the amount of milk powder, reduce the amount of breastmilk intake, and gradually increase the type of food intake, in order to prepare for the later weaning, add complementary foods to balance the nutrition to lay the foundation.
