Final answer:
Infants require about 50 calories per day for each pound they weigh to support their growth and development. This is a general guideline and individual needs may vary.
Step-by-step explanation:
The recommended amount of calories per day for each pound an infant weighs is approximately 50 calories. This intake can help support the rapid growth and development during the infant's first year of life. For example, if an infant weighs 20 pounds, the total daily caloric need would be around 1000 calories (20 pounds x 50 calories/pound). However, it is important to note that individual caloric needs can vary based on factors such as growth rate, metabolism, and overall health. It's best to consult with a healthcare provider for personalized dietary recommendations.
