How Breastfeeding Progress Is Calculated

Breastfeeding progress is calculated by comparing your baby’s current age to your total intended nursing duration. This comparison creates a clear percentage that shows how much of the journey is complete. We also check your goal against the World Health Organization's 24-month recommendation to see how it aligns with global health standards. Finally, we estimate daily milk needs using a standard multiplier based on age.

Milk Needs (oz) = 2.5 × Baby's Age (months)

Where:

  • Baby's Age is the current age in months.

This method provides a quick snapshot of your current lactation status and helps you plan effectively for the future.

What Your Breastfeeding Progress Means

Your progress number tells you exactly where you stand in your breastfeeding journey. It is a helpful way to visualize the time remaining and plan for future changes like introducing solids or returning to work.

  • Early Phase (0-25%): If you are in the early stages, focus on establishing a strong milk supply. Use the "Daily Feeding Sessions" result to track consistency during these crucial first months.
  • Mid-Journey (26-75%): You are well on your way. This is a good time to review the "Return to Work Timeline" to prepare for pumping schedules if you are employed.
  • Approaching Goal (76-100%): You are nearing the finish line. Use the "WHO Recommendation Compliance" metric to feel proud of meeting or exceeding health guidelines.

Important

Daily milk needs are estimates based on averages and may vary depending on your child’s weight, growth spurts, and overall health.

This calculator is for informational purposes only and does not constitute medical advice. Always consult a lactation consultant or pediatrician for concerns about feeding or growth.

To get the most accurate results, update your baby's age monthly as they grow and their nutritional needs change.
