What recommendation should a nurse practitioner give to a new father regarding whole milk for his 6-month-old son?

The recommendation to wait until at least 12 months of age to introduce whole milk to an infant is based on nutritional guidelines and the specific needs of a developing child. Up until the age of one year, infants require a diet that is rich in iron and other essential nutrients, which is best provided by breast milk or iron-fortified formula. Whole milk does not have enough iron and can also be difficult for infants to digest.

Introducing whole milk too early can lead to risks such as gastrointestinal distress, iron deficiency anemia, and even increased potential for allergic reactions or intolerance. At around 12 months, an infant's digestive system is more developed, and they can better handle whole milk as a protein and fat source, complementing their diet alongside solid foods.

This guideline helps ensure that infants receive a balanced diet during this critical period of growth and development. Other options might mislead caregivers into thinking that whole milk is appropriate sooner, which could compromise an infant's health and nutritional status.
