Formulae for infants contain sufficient calcium and normally infants do not need additional calcium supplementation. During growth and development, infants need sufficient calcium to promote bone development. Formula milk is usually more comprehensive in nutrition, containing calcium and other nutrients, so it does not need additional calcium supplementation to meet the needs of physical development. However, it is necessary to pay attention to the rational use of formula milk powder and master the prescribed amount to prevent the infant from malnutrition due to insufficient feeding of formula milk powder. When infants drink formula milk powder, they need to start adding complementary food around 6 months to meet more nutritional supply. If the infant has poor growth, it is necessary to go to the hospital in time, and ask the professional doctor to judge whether nutritional supplements are needed.
