Vitamin D in severe conditions

Do I need to give vitamin D to a newborn during breastfeeding? The results of numerous studies show that the introduction of micronutrient from the first days of life is necessary, as its concentration in breast milk is low and is slightly more than 10% of the recommended minimum (400 IU) daily norm for non-smelling. Even if you prescribe vitamin D to your mother during breastfeeding, its daily dose should once exceed the normal recommended WHO for an adult.
