## **Core Concept**
Inadequate breastfeeding in infants can lead to various clinical manifestations due to insufficient intake of milk, resulting in dehydration and malnutrition. Monitoring the infant's health and behavior is crucial to assess the adequacy of breastfeeding.

## **Why the Correct Answer is Right**
The correct answer, **D. Less than 6 wet diapers per day**, is an indicator of inadequate breastfeeding because it suggests that the infant is not consuming enough milk, leading to decreased urine output. Breastfed infants typically have 6-8 wet diapers per day due to the high water content of breast milk. Fewer wet diapers can indicate dehydration and insufficient milk intake.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is not provided, but typically, an option might suggest that an infant having more than 6 wet diapers per day is an indicator of inadequate breastfeeding, which is incorrect because more frequent wet diapers usually indicate adequate hydration.
- **Option B:** Similarly, this option is not provided but might inaccurately suggest that having 6-8 wet diapers per day is inadequate, which is not true as this range is normal for breastfed infants.
- **Option C:** Without the specific option provided, a common incorrect statement might be that an infant having a certain number of bowel movements per day is the best indicator of adequate breastfeeding. While bowel movements can be an indicator, the frequency can vary widely among breastfed infants, and urine output is a more reliable indicator of adequate milk intake.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that breastfed infants typically have 6-8 **wet diapers** per day and 3-4 **stool movements** per day in the first few weeks. Fewer than 6 wet diapers per day can be an early sign of inadequate milk intake and potential dehydration.

## **Correct Answer: D. Less than 6 wet diapers per day**
