Worked Example

Let's look at a practical example to understand how the calculator works.

Example: Your baby weighed 8 pounds at birth. After 2 weeks, their current weight is 7.5 pounds.

Using the formula:

Weight Loss Percentage = [(8 - 7.5) / 8] × 100 = 6.25%

This means your baby has lost 6.25% of their birth weight, which is within the normal range.

This example shows how the calculator helps you track your baby's weight loss and understand if it's within healthy limits.
