Final answer:
Infants and toddlers from 1 to 3 years old should typically consume about 1,000 to 1,400 calories each day, with variation based on individual factors like activity level and growth rate.
Step-by-step explanation:
From 1 to 3 years of age, infants and toddlers should typically consume about 1,000 to 1,400 calories per day. However, it is essential to note that the exact number can vary significantly based on each child's activity level, growth rate, and overall health. For example, a sedentary child might require fewer calories, while one who is very active or experiencing a rapid growth spurt may need more.
The guideline of 110 kcal/kg can be used for a more individualized calculation. This is especially important because, like adults, not every young child will fit perfectly into an average caloric intake range. Monitoring growth and health is crucial, ensuring nutritional needs are met without excessive calorie intake which could contribute to pediatric obesity.
