Flow

For the moments that matter.

Flow is an innovative addition to the lactation support toolbox. It is designed to visualize milk transfer from mother to baby during breastfeeding, reflecting the natural feeding process and offering insight into each infant’s unique pattern of suckling and swallowing.

What Flow does

01

Visualize Milk Transfer

A clear, medical-grade tube presents milk flow during breastfeeding, offering real-time insights into breastfeeding. Giving you a unique way to reassure the mother, teach, or troubleshoot.

02

Bridge the Communication Gap

Education is most effective through observation. Flow transforms abstract concepts into visual feedback, showing mothers what was once only possible to explain.

03

Build a Supportive Environment

Visible milk flow helps involve the entire family in the breastfeeding journey. Providing tangible proof of milk production can empower mothers and gain support from those around them.
