Ask almost any New York City mom if she trusts her kidsâ nanny, and odds are she will say yes. Categorically, yes. This was true before an Upper West Side nanny allegedly murdered two of her charges last weekâand itâs true today.

Now ask these same moms how much they know about their nanniesâtheir love lives, their financial histories, what they do over the weekendâand the answer might seem surprising: some of us know very little.
In an informal survey of moms I know, several didnât know their nanniesâ home addresses. Most were unfamiliar with their nanniesâ financial lives (with the exception of one friend who set up a 401(k) for her nanny).
A few had detailed information about health problemsâsome provided their nannies with health insuranceâbut most werenât aware of past or present illnesses.
Emergency contact numbers? Some yes; others, no.
Boyfriends or husbands? Names, but not always numbers.
Criminal background check or hidden camera? No. Across the board, no.
I asked if anyone had ever returned to the house unexpectedly just to check up. No one had.
And finally, I wanted to know how often they talk to their nannies about their personal lives. The answers ranged from âperiodicallyâ to âsometimesâ to âall the time.â Some didnât want to pry, others were stymied by language barriers.
To be clear, all of these moms are great moms. And a background check or hidden camera would probably not have prevented Yoselyn Ortega from allegedly killing the two kids to whom friends and neighbors said she was âdevoted.â What might have motivated Ortega is still a mystery. Friends have said sheâd had a rough year, losing her apartment, hitting financial problems, and behaving unlike the happy, friendly woman theyâd always known. Itâs unclear whether Ortega discussed any of this with her employers, Kevin and Marina Krim, or whether she had sought help.
Early reports suggest the Krims might have known Ortega better than most families know their caregivers. They had traveled to the Dominican Republic with her, and spent time with Ortegaâs own family. And they clearly trusted her. This had to be a freak and unpredictable crime. It had to be.
I have never traveled with the woman who watches over my two girls, the woman I have known for more than two years, who has helped raise them, teach them to talk, to sing, to love, and to be loved. When she arrives in the morning, she laughs the minute she sees them, and she is laughing when I come home at the end of the day. She takes credit for the people they are becoming, and sheâs right to. She would never hurt my kidsâin fact, if anyone else tried to hurt them, I believe she would punch them in the face.
Which is why I trust her completely. Yet in many ways, I barely know her. I know her boyfriendâs first name, but nothing else about him. I donât have her license plate number, donât know whether she sees a therapist, if sheâs having financial problems, or who I should call in her family in case of emergency. Iâm not friends with her on Facebook (I donât know if sheâs even on Facebook), and though I read the tweets of hundreds of strangers, I have never seen hers.
Itâs staggering, the difference in the degree to which I trust her and the degree to which I know her. But Iâm not sure the news that someone elseâs nanny might have done the unspeakable will change any of this. And Iâm not sure how well I have to know her to know my children are in good hands. As a friend of mine wrote, when I asked her about her relationship with her kidsâ former nanny: âI trusted her completely. I had to. Otherwise, it would have been a nightmare.â
