The world’s first breast milk monitor is a sleeper hit for parents at CES 2026 – here’s how it works

One of the biggest concerns for new parents who choose to breastfeed is, how do I know if my baby is getting enough milk? Coro, a new device created by Coroflow, accurately monitors breast milk intake in real-time, down to the 0.01 milliliters — the first product on the market to do so.

Coro is a silicone nipple shield with a patented micro-flow meter that measures milk intake, which you can view in a free app. The app translates the data into insights on breast milk volume and feeding trends for each breast to help new parents better understand their baby’s feeding patterns.

The nipple shield is as thin as a contact lens, similar to others breastfeeding people might use to protect the skin. As the milk flows through the shield, the amount is tracked live through the app.

Eighty-three percent of mothers in America start breastfeeding at birth, but by the time the baby is six months old, that number has dropped to 25% still exclusively breastfeeding, according to data from the US Centers for Disease Control and Prevention. 

“One of the biggest reasons globally why women stop breastfeeding is because of the concern around low supply,” Susie Benson, head of growth at Coroflo, told me at CES. “You can use this in the comfort of your own house, and it’s not invasive. Currently, there is no other way on the market to actually quantify this.” 

Coroflow’s co-founder Helen Barry, a doctor, had a baby boy who was tiny at birth, and had to track his weight gain through weekly weigh-ins and stressful pre- and post-feed weight checks. She couldn’t believe as a doctor that there wasn’t a better way to track feedings. Her husband, an engineer with a background in flow-sensing technology, helped develop Coro to help provide parents with more clear and immediate data, Benson said.

Coroflow will also become only breastfeeding repository in the world to help inform researchers about what a “normal” supply actually looks like. The company is currently working on a study with the University of California, Irvine, about baby development. 

On a personal note, to say that a product like this would have helped my breastfeeding journey is an understatement: When my daughter was born four years ago, she had a perfect latch, but was fussy and losing weight. It turned out I had very low supply, but it took far longer to figure that out and try to correct it than was ideal, and the experience took a toll on my postpartum mental health. If I had had a tool like Coro to tell me how much she was getting from the start, I could have adjusted far more quickly. Other parents I spoke to at CES said they felt the same, and wished this had been part of their breastfeeding experience.

At launch, the Coro will in one medium size, though a small and a large size are incoming as well. You can check the sizing guide to see if it will fit. The shield can be washed with soap and water, and is charged in a small carrying case, which can be connected to your phone.

Coro will be available in the US in September, at a retail price of $299.
