AI-Generated Summary

Key Takeaways

  • Baby monitor evolution: Nanit's AI-powered monitor goes beyond video surveillance to track infant sleep cycles, eye movements, wake durations, and self-soothing times, then delivers scored insights via app. The company targets the zero-to-ten age range and plans to expand into developmental milestone prediction, including crawling and speech timing specific to each child.
  • Wearable market scale: Approximately half of Americans currently use some form of health tracking device. The broader wearables market is approaching $100 billion in value. Companies like Whoop and Oura Ring are valued in the billions and moving toward IPOs, driven by AI-generated personalized recovery scores, sleep analysis, and daily readiness metrics.
  • Behavioral change mechanism: Whoop's "Whoop Age" metric — calculated from resting heart rate, sleep performance, and daily activity — proved more motivating than standard medical advice. One user, told his biological age was 37 but his Whoop Age was 44, began waking at 5AM daily for cardio and reduced his Whoop Age to 35 within one year.
  • Data privacy trade-off: Nanit states it does not sell user data or target ads against it, positioning its subscription fee as proof that customers are not the product. However, the company collects continuous video and biometric data from children's bedrooms, and its CEO envisions maintaining that data collection through age ten and beyond.
  • Intuition erosion risk: A pediatrician and multiple sources in the episode flag that constant data feedback may replace parents' ability to read infant cues directly. A researcher studying wearable users found that people optimizing wellness through these devices are predominantly already healthy, raising questions about whether the technology addresses genuine health gaps or amplifies existing anxiety.

What It Covers

NYT reporter Sapna Maheshwari examines the rapid expansion of health tracking technology from adult wearables like Whoop and Oura Ring into the baby monitor market, led by companies like Nanit, which recently raised $50 million and uses AI to analyze infant sleep, development, and behavior patterns.

Notable Moment

Maheshwari's mother, who raised three children without monitors, accidentally left the Nanit app running all night, drained her phone battery, and woke in a panic assuming the baby was in danger — only to find the infant sleeping peacefully, undercutting the device's core anxiety-reduction promise.

Episode Transcript

Somewhere in an achingly contemporary gallery right now, a woman is sitting across from a toilet, considering it, really giving it a chance. That kind of seeing takes hours. Rewind to twenty twenty two, mid fold, she had the thought you've had. Someone else could be doing this. She was right. The bag went out. The hours came back. Eventually, the toilet revealed itself. We'll take the laundry. You take the time. Start your backstory at rinse.com/gallery. Rinse. It's time to be great. From the New York Times, I'm Rachel Abrams, and this is The Daily. More and more people are wearing technology. Fitness bands, smart rings, biometric shirts. These devices help track everything from their heart rate to even the temperature of their skin. The latest frontier, health tech for babies, and it's being supercharged by AI. And so today, my colleague Sapna Mahjwari tells us about her family's experience with all of this health tracking technology. And we discuss whether it's helping us, just adding to our anxieties, or maybe both. It's Wednesday, September 23. Okay. So Subnet, as you know, we are here today to talk about not just wearable technology, but all kinds of technology that helps you track health data. And I just wanna lay my cards out on the table and say that I don't use any of this stuff. I don't have an Apple Watch. I don't use an Oura Ring. I'm very much of the mindset that I don't need to spend $300 on some kind of piece of jewelry that's gonna tell me that if I drink, I won't sleep very well. So do you think by the end of this episode, I will realize the error of my ways, or will I be more set in them? Great question. I don't know how you're going to feel, but I can tell you that I never thought I would be using a bunch of this technology or that my family would. And it all kind of crept into my life. How so? So I'm a mother of two. Uh-huh. And when my first kid was born, about four years ago, I was looking for a baby monitor. And at that time, as I did my research, everyone kept recommending this monitor called the Nanit. The Nanit. Okay. And tell us what the Nanit does. So the Nanit is a baby monitor that hooks up to your home Wi Fi and lives as an app on your phone. Mhmm. It's kind of like the eye of Sauron. It's grabbing data from the video footage and and logging web for the eye of Sauron. Yes. Is that really what you want watching your baby? Well, you know, you might you might not think so at first, but it it was pretty amazing. Uh-huh. So you open this app, and the app is tracking the baby's movements. Mhmm. It logs when they woke up, when they fell asleep. It can see when their eyes …
