Final answer:

To determine the daily caloric needs of infants and toddlers, their weight must be converted from pounds to kilograms, which is then multiplied by the specific caloric requirement for their age group. After calculations, an 8-month-old at 21 pounds needs approximately 933 calories, a 5-month-old at 13.5 pounds needs approximately 661 calories, and a toddler weighing 18.7 kg needs approximately 1777 calories per day.

Step-by-step explanation:

Calculating Daily Caloric Needs for Infants and Toddlers

To calculate the daily caloric needs of an infant or toddler, we need to convert the infant's weight from pounds to kilograms and then multiply by the age-specific caloric requirement.

  1. For an 8-month-old infant weighing 21 pounds:
    First, convert pounds to kilograms by dividing by 2.2046 (since 1 kg = 2.2046 pounds). That gives us approximately 9.525 kg. Then, multiply this by the caloric requirement:

    9.525 kg × 98 KCal/kg/day = 933.45 KCal/day.

    Rounded off, the infant would need approximately 933 calories per day.
  2. For a 5-month-old infant weighing 13.5 pounds:
    Again, convert pounds to kilograms which gives us approximately 6.123 kg. Then, multiply this by the caloric requirement:

    6.123 kg × 108 KCal/kg/day = 661.284 KCal/day.

    Rounded off, the infant would need approximately 661 calories per day.
  3. For a toddler weighing 18.7 kg with a requirement of 95 KCal/kg/day:
    Simply multiply the weight by the caloric requirement:

    18.7 kg × 95 KCal/kg/day = 1776.5 KCal/day.

    Rounded off, the toddler would need approximately 1777 calories per day.

These calculations are based on average daily requirements and may not be exact for every individual due to factors like activity level and metabolism.
