Got milk? This new wearable can tell you exactly how much.
Coro, a first-of-its-kind breastfeeding monitor from Irish startup Coroflo, made its debut this month at the 2026 Consumer Electronics Show in Las Vegas, where it snagged several awards, including Best Parent Tech.
At first glance, the device looks like a classic silicone nipple shield — the kind moms have been using for decades to help babies latch or to protect sore skin. But what sets it apart is the tiny, non-invasive sensor inside.
That patented sensor measures how much milk is flowing through the shield and sends the data to a smartphone app so moms can see exactly how much their baby is drinking in real time.
“It analyzes your data so that you can see week on week over time if you’re increasing or decreasing,” Susie Benson, head of growth at Coroflo, told The Post at CES, adding that the device also tracks the length of feedings and the total milk volume from each breast.
“We’re the first and only ones who’ve been able to quantify this.”
Breast case scenario
Breastfeeding comes with a long list of benefits for babies.
For starters, breast milk changes as the child grows — the mix of fats, sugars, water, protein and minerals adjusts to meet the baby’s needs.
It also delivers antibodies that help protect infants from infections and long-term illnesses. Studies show breastfed babies have a lower risk of developing asthma, eczema, obesity, Type 1 diabetes and some allergies, and they are less likely to suffer sudden infant death syndrome (SIDS).
And moms get perks too. Besides being cost-effective, breastfeeding may help with postpartum recovery and lower the risk of Type 2 diabetes, heart disease and certain cancers.
That’s why the American Academy of Pediatrics and the federal dietary guidelines for Americans recommend exclusive breastfeeding for about six months and continuing alongside other foods for at least a year when possible.
But most moms don’t make it that long.
Across the country, 83% of mothers start breastfeeding at birth — but by six months, only 55% of babies are still getting breast milk, according to the CDC.
“One of the biggest reasons is because of concern over low supply,” Benson said.
The truth is, experts say most moms actually do make enough milk to meet their baby’s needs. But factors like frequent feeding, short feeds and the feeling that breasts are heavy, sore or not full, can make women worry they aren’t producing enough.
Fussy, upset babies don’t help either, and many moms switch to bottle-feeding sooner than they intended simply because they feel unsure.
Coroflo co-founder and chief research officer Dr. Helen Barry was inspired to create the device after her own baby boy was born tiny, making weight gain a top priority.
At the time, the only way to check if he was getting enough breast milk was through weigh-ins or unreliable pre- and post-feeding checks, which made an already stressful time even harder.
So Barry teamed up with her husband, an engineer with flow-sensing expertise, and others to develop Coro, aiming to take the guesswork out of breastfeeding.
When can moms get it?
Coro launches next month in Europe and will be available in the US in September. The device is expected to retail for $299, and the companion app will be free to download and use.
At launch, Coro will come in one medium size, with small and large sizes coming later. Interested moms can check the sizing guide on Coroflo’s website to see if it will fit.
The device is simple to use and can be washed with soap and water. It comes with a small carrying case that charges the unit, and it works wirelessly with no extra hardware. It’s also BPA-free and does not contain other potentially harmful chemicals.
And while babies generally accept it in tests, Coroflo recommends practicing with a standard nipple shield first to see if your child will use it before purchasing.
