1. What is Infant Weight Loss Percentage?

The Infant Weight Loss Percentage measures how much weight a newborn has lost compared to their birth weight. It's an important indicator of feeding adequacy and overall health in the early days after birth.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( \text{Birth Weight} \) — The infant's weight at birth (kg)
• \( \text{Current Weight} \) — The infant's current weight (kg)

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

3. Importance of Monitoring Weight Loss

Details: Monitoring weight loss helps identify potential feeding problems, dehydration, or other health issues. Most newborns lose 5-7% of birth weight in the first few days and regain it by 10-14 days.

4. Using the Calculator

Tips: Enter both weights in kilograms (kg). For accurate results, use weights measured on the same scale under similar conditions (both naked or both diapered).

5. Frequently Asked Questions (FAQ)

Q1: What is normal weight loss for newborns?
A: 5-7% loss is typical in first 3-5 days. More than 10% loss may require evaluation.

Q2: When should I be concerned about weight loss?
A: If loss exceeds 10%, if weight loss continues beyond 5 days, or if baby shows signs of dehydration.

Q3: How often should newborns be weighed?
A: Typically at birth, 24-48 hours after birth, and at first pediatric visit (3-5 days old).

Q4: Does weight loss percentage differ for breastfed vs formula-fed babies?
A: Breastfed babies may lose slightly more weight initially but patterns are similar.

Q5: What if my baby's weight loss seems excessive?
A: Consult your pediatrician immediately for feeding assessment and possible intervention.
