So so tragic.
After each of my kids' birth I went down the rabbit hole of researching SIDS, and while extremely rare, the likelihood of your child dying from SIDS is higher at daycare. And usually when it happens it happens in the first week or so after the baby enters the facility. The likely reason for this is a change in sleep positioning. In the NY Times case, it appears that the baby was placed on the side.
In 2008, I remember overhearing the workers at our part-time facility talking about a recent class they were supposed to attend. One remarked about how "did you know you're supposed to place babies only on their backs now?" The Back to Sleep Campaign started in 1992! I think we just assume, especially as newbie parents, that those professionals who we pay to care for our kids know more than us. They likely do about how to soothe a baby, but especially if they are older grandmother types like the ones that are in our facility, they aren't abreast of the most recent recommendations.
We had an extremely tragic case here in my town in which a very well respected licensed daycare used a weighted blanket on a baby under one year old. The baby was placed on his stomach, which wasn't the problem, since the baby had been sleeping that way his whole life. But the weighted blanket placed over the lower half of his body in combination with his being on his stomach likely led to his death. But because of the way SIDS works, it was never conclusive. The facility was not shut down or affected by the case.
I'm sure there are parents on here who successfully have their babies sleep on their tummies. I'm not saying that is the problem (although I could never do it). The problem is when your child is used to sleeping one way and is placed by a caregiver in an entirely different way.
