1. What is Baby Weight Loss Percentage?

The baby weight loss percentage calculates how much weight a newborn has lost compared to their birth weight. It's an important metric for assessing newborn health and feeding adequacy in the early days after birth.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( \text{birth weight} \) — Baby's weight at birth (grams)
• \( \text{current weight} \) — Baby's current weight (grams)

Explanation: The formula compares the difference between birth weight and current weight relative to the original birth weight, expressed as a percentage.

3. Importance of Monitoring Weight Loss

Details: Newborns typically lose 5-7% of birth weight in first few days, with 10% or more loss potentially indicating feeding problems or other health issues requiring medical attention.

4. Using the Calculator

Tips: Enter birth weight and current weight in grams. Both values must be positive numbers. For accuracy, weigh baby at same time of day using the same scale.

5. Frequently Asked Questions (FAQ)

Q1: What is normal weight loss for a newborn?
A: 5-7% loss in first 3-5 days is typical for breastfed babies. Formula-fed babies may lose less. Most regain birth weight by 2 weeks.

Q2: When should I be concerned about weight loss?
A: Consult a pediatrician if loss exceeds 10% or if baby isn't regaining weight by day 5-7.

Q3: How often should I weigh my newborn?
A: Daily in first week if concerns exist, otherwise 2-3 times weekly until birth weight is regained.

Q4: Does this apply to premature babies?
A: Premature babies may have different weight loss patterns - follow your neonatal team's guidance.

Q5: How accurate does the weighing need to be?
A: Use a digital baby scale that measures to at least 10g increments for reliable results.
