Coroflo is an Irish maternal health company that makes Coro, a connected breastfeeding monitor. The product resembles a silicone nipple shield worn over the breast during feeding. A small sensor records milk transfer and sends the information to a phone as the baby drinks.

How it works
A miniature flow sensor inside the shield measures the movement of milk without touching the liquid directly. Software converts that signal into an estimated volume and shows intake in real time. The app also records feeding duration, switches between breasts and builds trends across multiple feeds.

Key considerations
Coro only works when both parent and baby can feed comfortably with a nipple shield, and one size may not suit everyone. It provides a snapshot of milk transfer rather than a full assessment of feeding or infant health. The product is newly launched, so broad independent evidence remains limited.
