Formula Explained

The amount of breast milk to put in a bottle is calculated based on your baby's age and weight. The formula used is:

Recommended Amount (ounces) = (Baby's Weight in Pounds × 2) + (Baby's Age in Months ÷ 2)

Recommended Amount (milliliters) = Recommended Amount (ounces) × 29.5735

This formula provides a general guideline for the amount of breast milk to put in a bottle. It takes into account both your baby's weight and age to ensure they receive the proper amount of nutrition.

Worked Example

Let's say you have a baby who is 3 months old and weighs 12 pounds. Using the formula:

Recommended Amount (ounces) = (12 × 2) + (3 ÷ 2) = 24 + 1.5 = 25.5 ounces

Recommended Amount (milliliters) = 25.5 × 29.5735 ≈ 750 milliliters

So, for a 3-month-old baby who weighs 12 pounds, you should put approximately 25.5 ounces (750 milliliters) of breast milk in a bottle.
