Newborn refers to from umbilical cord ligation to 28 days after birth of the baby, because the baby is small, insufficient sunlight exposure, insufficient vitamin D intake, easy to cause poor calcium absorption, will show some symptoms of poor sleep easy to be irritated. Cod liver oil is also called vitamin AD drops, which can promote the absorption of calcium and phosphorus in babies and prevent rickets caused by vitamin D deficiency.
