When our babies are little, keeping them hydrated and dry is important and something many parents stress over. Trying to remember how many wet ones your little one has had in a 24-hour period is tough when you’re insanely sleep-deprived, you know?

That’s why these “smart diaper” concept from Pampers is so interesting. The brand’s high-tech diaper system, Lumi, which sees sensors attached to diapers to sense wetness (it doesn’t track bowel movements, just urine). The sensors work in concert with a Wi-Fi baby monitor and an app that lets parents keep track of baby’s diaper situation and lets them know when the baby needs to be changed.

According to a tweet from Pampers, this is “the world’s first all-in-one connected care system that is revolutionizing baby monitoring” and is in partnership with tech giants Logitech and Verily.

While wearable tech is nothing new this is the first time we’ve seen this sort of technology utilized for a diaper.

So how does this technology work, exactly? As Pampers explains, the sensor attaches to the front of the diaper and sends a signal to the app when a diaper change is in order—it can even tell a parent whether the diaper is merely “wet” or “very wet.” The app tracks all changes, which can eliminate that whole “how long ago was the baby’s last wet diaper?” dilemma new parents know all too well. The connected app also allows parents to track sleep and feedings, too, and the monitor is, well, a video monitor.

If you’re squeamish about putting a piece of technology directly on your baby, we get it. This is, after all, uncharted territory—and for some parents, it may raise questions about how large a role technology should play in a child’s life.

As the Washington Post reports, some privacy experts worry about putting this kind of personal data online (Pampers says the data will be secure). And as CNN reports, some experts say there can be such a thing as too much data, and are concerned that detailed tracking of data could make some parents more anxious instead of reliving stress.
