Which statement best summarizes essential newborn nutrition and supplementation?

• A. Breast milk is preferred; formula is acceptable; vitamin D supplementation for breastfed infants; iron supplementation considerations based on age and intake.
• B. Formula is preferred over breast milk.
• C. Vitamin D supplementation is unnecessary for all infants.
• D. Iron supplementation is always required for all newborns.

Answer: (A)

Essential newborn nutrition centers on breast milk as the preferred source, with formula as a safe alternative when breastfeeding isn’t possible, and on specific vitamin and mineral supplementation based on how the baby is fed and their age. Breast milk provides ideal nutrients and immune protection, so it’s the first choice. If breastfeeding isn’t feasible, infant formula supports growth as a suitable substitute. Vitamin D supplementation is recommended for breastfed infants (and for those not receiving enough vitamin D from formula) to prevent deficiencies, typically 400 IU daily starting early in infancy. Iron needs aren’t the same for every baby: formula-fed infants usually get iron from their formula, while exclusively breastfed babies often require iron supplementation or iron-rich complementary foods starting around 4–6 months, with adjustments for preterm or other risk factors. This combination reflects current guidance and explains why choosing breast milk as the preferred option, acknowledging the role of formula, vitamin D needs for breastfed infants, and the age- and intake–dependent approach to iron supplementation.
