A nurse is providing teaching to the parent of a 10-month-old infant who is having difficulty eating. The parent is feeding their infant goat milk. Which of the following instructions should the nurse include?

A. Goat milk lacks the necessary nutrients (such as folic acid and vitamin B12) for infants and should not be used as the sole source of nutrition. Commercially prepared infant formula is the best alternative to breast milk for infants over 6 months old. B. Soy milk is not recommended for infants unless specifically prescribed, as it lacks essential nutrients needed for proper growth. C. Warming goat milk does not address the underlying issue of inadequate nutrition. D. Reinitiating breastfeeding is ideal if the mother can, as breast milk provides optimal nutrition, but the main concern here is the type of milk being fed to the infant.
