Newborns generally do not need special calcium supplements, as long as they are fed an adequate amount on a daily basis to meet their calcium needs. If the newborn is a premature baby, a multiple birth, or if there is a low birth weight or a severe calcium deficiency in the nursing mother, the doctor will provide calcium supplements to the newborn. This is mainly done by drinking formula and having the nursing mother take calcium supplements so that the newborn can also get calcium while breastfeeding, and not by blindly giving calcium supplements to the newborn on their own. For newborns who need calcium supplementation, breastfeeding mothers can take calcium supplements under the guidance of doctors, such as intake of calcium gluconate, calcium amino acid chelate and other calcium supplements that can be easily absorbed. When their own calcium is sufficient, the calcium content in breast milk will also rise, and newborns will be able to supplement sufficient calcium through breastfeeding. If breast milk is not enough, you can choose formula, in which the nutrients are scientifically proportioned, comprehensive, balanced and suitable for newborns. Newborns can also take vitamin D supplements during calcium supplementation to help promote the absorption of calcium. You can take your newborn to the sun every day, preferably in the morning or afternoon when the sun is soft, avoiding strong sunlight exposure.
