From ancient times to the present day, the sharing of breast milk has had an interesting history from myth to misconception to a revolution of support by global agencies such as the World Health Organisation and UNICEF. This month’s blog touches upon the history of breast milk collection and analysis past, present, and future.


In ancient times, the ‘collection’ of human milk was simply nursing of the infant by family members, friends, or even strangers. The earliest recorded account was around 1800 BC during the Babylonian Code of Hammurabi. Between 100 and 400AD, an analysis of determining the milk’s quality and consistency was done using the fingernail test by placing a drop of breast milk on the nail. If the milk ran when the finger moved – too watery. If when the fingernail was turned downward, and the milk clung to the nail – too thick.

“It takes a village to raise a child” – African proverb.

The wet nurse’s evolution went from a community of family members and friends helping one another to women who served the wealthy. In fact, a wet nurse was a reputable, well-paying profession that earned more than a general labourer during the Victoria era.

As the popularity of wet nursing declined by the mid-19th century with human milk being replaced by alternative animal milk sources, a physician named Theodor Escherich led the way in pediatric infectious disease research. He discovered that breastfed babies’ intestinal bacteria greatly contrasted with infants fed with an animal milk alternative. Under the tutelage of Escheric, who in 1902 became the Chair of Pediatrics at the University of Vienna and Director of the St. Anna Children’s Hospital in Vienna, Vienna opened up the very first human milk bank in 1909. Human milk was pooled and pasteurized before distribution as milk analysers weren’t invented until the 1980s for the dairy industry, with human milk analysers to follow years later.


Today, there are hundreds of human milk banks worldwide of individual milk banks overseen by various national associations such as the European Milk Bank Association, Human Milk Banking Association of North America and the Rede Brasileira de Bancos de Leite Humano in Brazil. Women generously donate their breast milk to help the most vulnerable low-birth-weight infants in hospitals’ Neonatal Intensive Care Units.

Human milk banks are the gateway to supplying breast milk to hospitals. Their service is essential as they are “responsible for recruiting breast milk donors, collecting donated milk, and then processing, screening, storing, and distributing the milk to meet infants’ specific needs for optimal health.” (PATH report on Strengthening Human Milk Banking – A Global Implementation Framework). At times, the screening process may also include the use of a human milk analyser to measure the macronutrient content in breast milk, like fat, protein, and energy. This additional information assists NICU doctors to decide the type and amount of fortification required to supplement the breast milk given to meet each preterm infant’s needs.

Early in the development of our Preemie system, we interviewed several milk bank managers and neonatologists to get a better understanding of their needs for human milk analysis. It was important for us to develop an end-to-end solution for precise human milk analysis that met their needs. From these interviews we heard the following comments:

  • “It would be amazing to have software that could do the fortification calculations.

  • “We need software that can track the nutritional intake and correlate it to the infant’s growth.

  • “It would be great to have a smaller device that rapidly and easily tests the donor milk composition”

  • “We want to use as little milk as possible while performing the composition analysis.”

  • “We need to automate the process of fortification, and discard manual calculations;

  • “We need an affordable device that can test the milk freshness so we know if we should use the milk for infant feeding.”

  • “I need a simple and easy-to-use device that can test the milk composition but that doesn’t require recurrent calibrations.”

  • “It would be great if after testing the donor’s milk we could print a nutritional label with that information.”

  • “Would be great if we could test several donor milks and have the software tell us what milk should be pooled together so as to optimize the pooled milk with the highest possible nutritional quality.”



Based on the feedback, we are currently developing our Preemie System that can meet the requirements and needs of NICUs and of HMBs. You spoke and we listened!
