Use this baby bottle calculator to determine the appropriate amount of formula or breast milk your baby should receive per feeding. The calculator considers your baby's age, weight, and feeding type to provide accurate recommendations.
How to Use This Calculator
To calculate the recommended feeding amount for your baby:
- Enter your baby's age in months
- Enter your baby's weight in pounds or kilograms
- Select the feeding type (formula or breast milk)
- Click "Calculate" to see the recommended amount
The calculator will display the recommended amount per feeding in ounces and milliliters, along with a chart showing the feeding progression over time.
Formula Used
The recommended feeding amount is calculated based on standard pediatric guidelines:
- For babies under 6 months: 1.5-2.5 oz (45-75 ml) per feeding
- For babies 6-12 months: 3-4 oz (90-120 ml) per feeding
- For babies over 12 months: 4-6 oz (120-180 ml) per feeding
The calculator uses these guidelines to provide age-appropriate recommendations.
For more precise measurements, the calculator converts the recommended amount to milliliters (ml) using the conversion factor 1 oz ≈ 29.57 ml.
Worked Example
Let's calculate the recommended feeding amount for a 4-month-old baby weighing 12 pounds:
- Enter baby's age: 4 months
- Enter baby's weight: 12 pounds
- Select feeding type: Formula
- Click "Calculate"
The calculator will display:
- Recommended amount: 1.5-2.5 oz (45-75 ml) per feeding
- This is based on standard pediatric guidelines for babies under 6 months
The chart will show how the recommended amount changes as the baby grows.
Tracking Baby's Feeding
To track your baby's feeding:
- Record the amount given each feeding

Tracking feeding amounts helps ensure your baby is getting enough nutrition and allows you to adjust feeding schedules as needed.
FAQ
How often should I feed my baby?
Newborns should be fed every 2-3 hours, gradually increasing to every 3-4 hours as your baby grows. Always feed your baby on demand in addition to scheduled feedings.
What if my baby refuses to finish a feeding?
If your baby refuses to finish a feeding, try offering smaller amounts more frequently. Consult your pediatrician if you're concerned about your baby's weight gain or growth.
Can I use this calculator for breastfed babies?
Yes, the calculator provides guidelines for both formula-fed and breastfed babies. Breastfed babies may need slightly more frequent feedings, but the calculator provides a good starting point.
When should I introduce solid foods?
Most pediatricians recommend introducing solid foods around 6 months of age, when your baby shows interest in solids and can sit up with support.
