Worked Examples

Example 1: Normal Weight Loss

If your baby weighed 7.5 lbs at birth and now weighs 7.2 lbs:

Weight Loss Percentage = [(7.5 - 7.2) / 7.5] × 100 = 4%

This indicates normal weight loss for a newborn.

Example 2: Moderate Weight Loss

If your baby weighed 8 lbs at birth and now weighs 7.2 lbs:

Weight Loss Percentage = [(8 - 7.2) / 8] × 100 = 10%

This suggests moderate weight loss, which may warrant a consultation with a healthcare provider.
