**Core Concept**
HIV-infected children require special nutritional care due to increased energy expenditure, malabsorption, and opportunistic infections. Proper feeding management is crucial for their growth and development.

**Why the Correct Answer is Right**
Infants with HIV infection are at a higher risk of malnutrition due to chronic illness, diarrhea, and vomiting. The World Health Organization recommends exclusive breastfeeding for the first 6 months, followed by continued breastfeeding along with complementary foods until 2 years of age or beyond. This approach helps in reducing the risk of mother-to-child transmission of HIV and provides essential nutrients for the child's growth.

**Why Each Wrong Option is Incorrect**
**Option A:** This option may imply that HIV-infected children should be formula-fed exclusively, which is not recommended due to the risk of malnutrition and increased cost.
**Option B:** This option suggests that HIV-infected children should be fed a diet rich in protein and fat, which may not be necessary and could lead to weight gain.
**Option C:** This option implies that HIV-infected children should be fed a diet low in calories, which could exacerbate malnutrition and weaken their immune system.

**Clinical Pearl / High-Yield Fact**
HIV-infected children require regular monitoring of their nutritional status, including weight, height, and mid-upper arm circumference, to ensure they receive the necessary care and support for optimal growth and development.

**Correct Answer:** A.
