Three Questions About…Baby Sleep

We spoke with Dr. Harvey Karp, inventor of the SNOO, about soothing the ills of modern parenthood.

Whether or not you know Dr. Harvey Karp by name, you’ve probably absorbed his influence on baby sleep and soothing. The resurgence of the swaddle? The ubiquity of white noise in babies’ rooms? Cribbed (no pun intended) from Dr. Karp’s bestselling book The Happiest Baby on the Block. And he’s probably best known for SNOO, a pricey “smart bassinet” that rocks and jiggles a strapped-in baby all night long. In my ninth month of pregnancy, I spoke with Dr. Karp about the evolution of his signature product, what nuclear families are missing, and why sleep is a feminist issue.

When SNOO first came out in 2016, it was a signifier of luxury–Beyoncé and Jay Z reportedly owned several. Now, it’s used in hospitals, including to soothe babies who were born dependent on opiates, and you’re working to have SNOO covered by Medicaid. That seems like quite a shift–how did that come about? 

Yes, SNOO was really known as this bougie baby bed in the beginning, but the goal was always to make it accessible to everyone. We built the bed to be reused over and over again. It’s sort of the way breast pumps started out: There were these industrial breast pumps and they were too expensive for people to buy, but you could rent them. And so, our goal was always to have SNOO be either rented or for free, and not to be purchased and owned. 

We have a project going on in Wisconsin right now, where hundreds of [SNOOs] are being given to families who have premature infants, mostly Medicaid recipients. Our job is to develop the science to convince Medicaid payers that we can save money and improve outcomes. We’ve also had a lot of success with companies offering SNOO as an employee benefit. Now, tens of thousands of people get a free SNOO rental from their employer, from big companies like Dunkin’ Donuts to the largest duck farm in America.

You often say that SNOO can help replenish what we’ve lost in terms of the extended family and support for new parents. But I think some people still feel a little funny about swapping out human cuddles for a machine. What do you say to that?

Yes, a hundred years ago, and for the entire history of humanity, we had extended families, and people lived right next door to their grandmother, their aunt, their sister, and everybody shared the work. Then we moved to the city or moved hours away from our family, and women got more work responsibilities outside the home. This became pretty crushing on parents, especially single parents. So the SNOO goal is to be a helper. It’s there in the home when you’re cooking dinner, when you’re taking a shower, when you’re playing with your three-year-old, when you are getting some sleep. It’s not set it and forget it, but it can give you 20 to 30 minutes here and there, as well as giving an extra hour or even up to two hours of extra sleep.

In the womb, the baby is being held 24/7. Then they’re born, and 12 hours a day we put them in a dark quiet room. That’s sensory deprivation compared to what they had before they were born. So why, because you only have a few people in your family, should the baby miss out? SNOO…doesn’t replace what the parents would be doing, because no one can rock them all night long. It just gives the baby a little extra.

When I had my first baby, sleep was a locus of inequality in my relationship–my male partner was obviously getting more of it, especially because I was riddled with anxiety about whether my baby was safe. Sleep became a feminist issue in my mind. How do you see SNOO responding to these gender dynamics, which seem to be common?

We’ve definitely moved in the direction of gender equality, but we’re still far from it. Even when the baby is sleeping, sometimes moms are awake and anxious knowing that they have to get up in three hours. SNOO can help with that: There have been studies reporting that SNOO reduces maternal depression and maternal stress. There are five things that trigger depression and anxiety that SNOO improves: up to 41 minutes more sleep for mothers per night, reduced infant crying, less anxiety that the baby is in danger, the feeling that you have a support system, and [the fact that it] makes you feel like you’ve gotten things managed better. Also, men very often take on the role of being the sleep experts when they have a SNOO in the house. Men want to manage this gadget. That takes a burden off the shoulders of the mom.
