TW: discussion of sudden and sleep-related infant death
I am extremely concerned that the above reblog cuts out (without even indicating the cut with an elipses) a VITAL paragraph when quoting the article.
After the paragraph about preventing SIDS through various precautions, it should read "While safe sleep practices are still important for protecting infants, many children whose parents took every precaution still died from SIDS. These parents were left with immense guilt, wondering if they could have prevented their baby’s death."
Without this paragraph, the text as widely spread on Tumblr (where following through to the original article is low) implies that precautions such as laying baby on their back, keeping toys out of cribs, and temperature regulation are not important. This is an extremely dangerous take to spread uncritically.
While it's important to understand any biological factors contributing to infant deaths, doing so at the expense of the well-established biomechanical dangers of unsafe sleep practices can make people think that safe sleeping directives (baby is Alone, on their Back, in a Crib or bassinet with appropriate bedding and without toys) are misguided or overstated. Even in light of this discovery, however, suffocation due to unsafe sleep practices remains a significant risk to infants (making up about a third of unexpected infant deaths each year, with the other third being attributed to SIDS or unknown causes, numbers that are complicated by various social factors, including variation in medical expertise and opinion among medical examiners and coroners that can lead deaths to be misclassified as SIDS even if a potential airway obstruction is known).
While this part of my professional life isn't something I go into online, my line of work is such that--over my lifetime--I have held and washed far, far more dead children than living. Some have been SIDS deaths, some ultimately found to be related to other previously undiagnosed congenital issue, but in the overwhelming majority of the cases I've seen, suffocation due to an unsafe sleep environment was the sole cause or at minimum a major contributing factor of death. Infants with faces pressed against a stuffed animal or fold in a blanket, infants who fell off an adult bed or sleeping caregiver and become wedged, infants unintentionally smothered by a sleeping or incapacitated adult's body weight, infants laid down on an adult pillow, and on and on and on and on. In almost all these cases the adults thought they were being safe, because they had done the same thing without incident for most of the child's life or with previous children. That's why Safe to Sleep programs are so important.
If people walk away from the news of this enzyme discovery thinking that internal biochemical factors are solely to blame for sleep related deaths in infants rather than an explanation for why some infants die even if all recomended precautions have been taken, the infant mortality rate will not improve, and families will continue to suffer preventable tragedies.
