For newborns, the best way to feed is breastfeeding, if exclusive breastfeeding can not meet the needs of newborns, you can choose mixed feeding. 1. Mixed feeding: When a newborn is mixed feeding, the newborn’s mammary gland stimulation to the mother is reduced, which is not conducive to the mother’s ability to maintain an adequate amount of milk, and does not ensure adequate nutrition when breastfeeding. When mixed feeding, the newborn’s digestive system is not yet mature, it is easy to cause bloating and diarrhea and other symptoms. However, it is suitable for the situation that exclusive breastfeeding cannot meet the needs of newborns. 2. Breastfeeding: Breastfeeding can increase the bond between mother and child. Breastmilk is rich in easily absorbed proteins, fats and sugars, which are easily digested and absorbed by newborns. Breastmilk also contains a variety of antibodies and immune factors, which can enhance the resistance and physical quality of newborns.
