Back in 2002, my third daughter was born 11 weeks premature. Weighing just 1 pound, 1 ounce, she was the smallest living thing I had ever held in my hands.
From that day on, I had a constant need to monitor her weight and the amount of milk she had eaten to ensure she had the best chance of healthy development. A new tool for breastfeeding called Coro could have helped me tremendously back then.
Coro is a silicone nipple shield with an integrated flow rate monitor that measures breast milk delivery with an accuracy of 0.01 milliliters. Its companion app lets you see the flow of milk in real-time, so you can easily monitor your baby's intake. Announced at CES 2026, it's due for release in September 2026 alongside a free monitoring app and Apple Watch app.
When we were measuring our little preemie's weight, we were constantly on the scales, and we could only guess at the amount of milk she was drinking. If we were feeding with formula, we could have kept an eye on the volume, but breastfeeding mothers can't do the same.
Coro intends to address this issue with real-time monitoring and an app that will track your baby's milk intake over time, as well as across each breast. The peace of mind that would have given us as new parents of a tiny baby would have been easily worth the $299 estimated price.
