They suggest a causative link in the article: carbon dioxide concentrations near the infant's nose and mouth which can cause suffocation.

I am going to go ahead and call BS on gas concentration increasing beyond noise level in even the most stale air environment. Even assuming that could be the case, the area around an infant is practically a hurricane on the scale we're talking about- the smallest movement, the slightest temperature gradient, the tiniest breath of the infant is going to be very disruptive to any local gas pockets. It's incredibly unlikely to be related unless infants are sensitive to the tiniest possible CO2 concentration changes, in which case sitting in a car or other sealed space would be dramatically more likely to cause infant death.

  unless infants are sensitive to the tiniest possible CO2 concentration changes,. Yes, they are. This is documented scientific fact. in which case sitting in a car or other sealed space would be dramatically more likely to cause infant death This is also not recommended. Note that nearly all modern automatically vent new air into the vehicle...

  You have, in fact, lit upon the mechanism at play: some infants are sensitive to even tiny CO2 concentration changes, particularly when risk factors are combined. There is a reflex where instead of breathing more when CO2 levels rise, infants stop breathing all together: https://www.frontiersin.org/articles/10.3389/fneur.2015.00220/full https://www.frontiersin.org/articles/10.3389/fneur.2015.0022... While a car is moving it has ventilation, and it's illegal to leave an infant alone in a parked car in part for this very reason. But sleeping in a car seat is one of the risk factors for SIDs.

    huh. I guess I learned something, thanks. I guess it makes some sense - infants are somewhat still in the transitory phase between breathing being a fun side activity and breathing being essential to living.
