In Nigeria, formula is seen by many as a status symbol. Despite the clear health and developmental benefits of breastfeeding, only 29 percent of Nigerian mothers practice exclusive breastfeeding for the first six months.

Cultural pressure, workplace challenges, and the aggressive marketing of infant formula contribute to this low rate. At the same time, formula is extremely expensive, often taking up more than 30 percent of a family’s monthly income.

Mothers who choose to breastfeed are saving real money, but that saving is neither visible nor valued. Financial systems do not track it, and public health systems do not reward it. The absence of recognition reinforces the false perception that breastfeeding has no tangible worth.

In Nigeria, mothers save a significant amount of money by breastfeeding, but that saving is invisible. It is not recorded, not rewarded, and not linked to any form of financial growth.

The opportunity was to use real time local data to measure and translate the value of breastfeeding into a personal financial benefit. But doing this in a way that is relevant to mothers requires more than just data collection.

It requires making that data emotional, empowering, and easy to engage with inside a digital product.

Breastmilk Money is the first bank feature that turns breastfeeding into compound savings. Mothers input their baby’s age and feeding level into the Herconomy app.

The app uses WHO breastfeeding standards to estimate how many milliliters of breastmilk are produced per day. It then cross references this with Nigeria’s National Bureau of Statistics to calculate the local market price of the equivalent formula.

That amount is transferred into a sub account that earns 14.3% interest, reflecting the proven cognitive development gains of breastfeeding. All calculations update monthly based on live price data and the baby's developmental stage.

Beyond the backend logic, the data was made human. The app uses visual feedback, celebratory milestones, and animated meters to show mothers the real value of their care work. The design makes complex data feel personal. The more mothers feed, the more they see their account grow. The more they grow, the more confidence they gain.

In its first three months Over 35 million US dollars in potential savings were calculated across users, Herconomy app sign ups increased fivefold, Breastfeeding rates rose by 9 percent in key regions, The campaign generated over 150 million dollars in earned media.

Breastmilk Money showed how data could change perception. It turned breastfeeding into a financial behavior and made women’s invisible contributions measurable, meaningful, and profitable. What was once emotional labor became a visible investment in both health and wealth.
