  3. Select your current feeding status
  4. Provide your return to work timeline
  5. Adjust the daily feeding sessions slider
  6. Click Calculate to see your personalized breastfeeding journey analysis

Formula Used

Progress Percentage = (Current Age / Intended Duration) × 100

Where:

  • Current Age = Baby's age in months
  • Intended Duration = Planned breastfeeding duration in months
  • WHO Recommendation = 24 months of breastfeeding

Example Calculation

Real-World Scenario:

Sarah has a 6-month-old baby and plans to breastfeed for 18 months. She's currently exclusively breastfeeding and plans to return to work when her baby is 9 months old.

Given:

  • Baby's Age = 6 months
  • Intended Duration = 18 months
  • Feeding Status = Exclusive Breastfeeding
  • Return to Work = 9 months

Calculation:

Progress Percentage = (6 / 18) × 100 = 33.3%

Remaining Duration = 18 - 6 = 12 months

Result: Sarah has completed 33.3% of her intended breastfeeding journey with 12 months remaining. She should prepare for transitioning to expressed milk when she returns to work in 3 months.

Common Mistakes & Tips

Night feedings are crucial for milk supply and baby's growth. Many mothers mistakenly focus only on daytime feedings when planning their breastfeeding journey. Include night feedings in your total daily count for accurate planning.

Many mothers don't prepare for the transition back to work until it's too late. Start planning pumping schedules and storage options at least 1-2 months before returning to work to ensure a smooth transition.

Frequently Asked Questions

The World Health Organization recommends exclusive breastfeeding for the first 6 months of life, followed by continued breastfeeding with appropriate complementary foods up to 2 years of age or beyond.

Newborns typically breastfeed 8-12 times in 24 hours. As babies grow, the frequency may decrease to 4-6 times per day, but the duration of each feeding may increase. Follow your baby's hunger cues rather than a strict schedule.

To maintain milk supply when returning to work: establish a pumping schedule that mimics your baby's feeding pattern, stay hydrated, eat a balanced diet, consider using a hands-free pumping bra, and breastfeed your baby when you're together. Building a freezer stash before returning to work can also help ease the transition.
