Final answer:
The recommended number of calories per day for each pound an infant weighs is 50-60 calories, which corresponds to about 110 calories per kilogram of body weight for infants under 1 year.
Step-by-step explanation:
The recommended number of calories per day for each pound an infant weighs is 50-60 calories. For infants under 1 year, the caloric requirement is roughly 110 calories per kilogram of body weight, which translates to about 50-60 calories per pound, considering 1 kilogram equals approximately 2.2 pounds. It is imperative to note that caloric needs for infants can vary depending on factors such as growth rate, metabolism, and activity level. The importance of providing the correct amount of calories is crucial for the proper development and growth of the infant.
A healthy baby may require approximately 578 kcal/day, considering the energy value of milk, which is typically essential for infants' development. This need for calories scales with the infant's weight, ensuring they receive adequate nutrition for their developmental stage.
