It can provide babies with all the nutrients they need for their development and improve their immunity; and for mothers, it can promote uterine regeneration, delay the return of menstruation and the time of ovulation, and facilitate the recovery of their post-partum figures. 1. Benefits for infants: (1) Provide a variety of nutrients: breast milk is rich in proteins, lipids, vitamins, inorganic salts, etc., and all kinds of nutrients can be easily absorbed and utilized by infants and young children, which can promote their growth and development.
