1. What is Percentage Weight Loss in Babies?

Percentage weight loss in newborns is a measure of how much weight a baby has lost compared to their birth weight. It's normal for newborns to lose some weight in the first few days after birth, but excessive weight loss may indicate feeding problems or other health issues.

2. How Does the Calculator Work?

The calculator uses the percentage weight loss formula:

Where:

• Birth Weight — Baby's weight at birth (kg)
• Current Weight — Baby's current weight (kg)

Explanation: The formula calculates what percentage of the original birth weight has been lost.

3. Importance of Monitoring Weight Loss

Details: Monitoring weight loss helps identify potential feeding issues early. Normal newborns typically lose 5-7% of birth weight in the first few days and regain it by 10-14 days. Losses >10% may require intervention.

4. Using the Calculator

Tips: Enter birth weight and current weight in kilograms. Both values must be positive numbers. The calculator will show the percentage of weight lost since birth.
