Scorah has also encountered critics, who speculate that even if they’d been with their parents, babies like Karl and Leo would have died anyway. Rachel Y. Moon, a professor of pediatrics at the University of Virginia School of Medicine and one of the researchers who discovered the correlation between SIDS and starting day care, acknowledges that it’s often impossible to know. “Most of these deaths are not clear- cut. But I really do believe that babies are stressed out when they start day care,” says Moon. “Any child care provider will tell you, they can walk into the day care and pick out the new baby, because that’s the one who is crying, crying, crying.” Moon hypothesizes that all this stress makes it harder for the baby to fall asleep; when he finally does, he’s so exhausted he may fall into a deeper sleep than usual. “We also know that day care providers are more likely to put babies down on their stomachs, because they stay asleep” better, she says. This raises the risk for asphyxiation in all babies, and for SIDS, in those babies with that genetic predisposition. Both she and Jacobson emphasize that these deaths are often the result of good intentions gone wrong. “Think about how nervous everyone is about a baby coming to day care for the first time,” says Jacobson. “Parents want them to be comfortable, so they may bring more blankets or loveys from home to put in the crib, which can pose a suffocation risk.” Her organization has been a key partner in the American Academy of Pediatrics’ national Back to Sleep and Safe Sleep Saves Lives campaigns, which, by educating parents, caregivers, and medical professionals that infants are safest sleeping on their backs, has helped to reduce the frequency of SIDS by 50 percent since it began in the early 1990s.
