Scientific Rationale

Breastfeeding establishment is the process by which milk supply and breastfeeding dynamics are developed in the first days to weeks postpartum.

This is also reflected in milk compositional changes transitioning from colostrum to mature milk. Early identification and management of delays can improve outcomes for successful exclusive breastfeeding.

By looking at the milk itself, the Mylee can help identify early trends within this dynamic process, in real time, from the first days after birth.

High levels of milk electrolytes, such as sodium and chloride, may signal delays in milk production and potential breastfeeding challenges.

Patented technology

The MyLee system comprises a hand-held milk sensing device with a dual-sensor system configured to reliably measure milk sample conductivity in small (350ul) human milk sample, and a smartphone application implementing algorithms for data collection, processing, and visualization in a user-friendly manner.

Testing and Validation

The system was subjected to rigorous device performance testing including linearity, precision, accuracy, and repeatability using standard solutions and breast milk specimens, and was compared to lab-grade analysers.

Development and Design

The MyLee was designed by engineers for simple and precise operation, to be used with miniature milk samples, by moms, at home. Our team has tested several rounds of prototypes before bringing the sleek, easily operated, robust and accurate tool to mother’s hands. 

Association with Sodium ion levels

Laboratory analysis of a set of breast milk samples demonstrated a strong reverse correlation between system's MM% results and milk sodium ion (Na+) levels, a well-studied biomarker for secretory activation states and lactation adequacy

Milk Maturation Percent

A novel parameter for tracking secretory activation progress

Milk maturation % chart

Follow each side seperately. Color coded relative to population set. Expected to evolve from low % to 100% during the first weeks after birth. Allows the identification of delay relative to expected, difference between sides, and response to change in routine.
