I’ve done a good amount of research into SIDS, and if you look at the data the cases did not start rising until the female empowerment movements and sexual revolutions. When you look closer at the data you notice that a majority of the cases are from black mothers usually single mothers, and also native Americans. A very small percentage of deaths are due to respiration problems, the next percentage is due to negligence due to exhaustion, and the larger percentage is suspected to be intentional suffocation of the child, this most often always happens when dad is at work/not home, or in the picture to begin with. The only witness being the mother they will say that is how they found the child. As you said the pandemic forced a lot of people to have others with them preventing them from carrying out this vile action. It is hard to adjust to the changes of new parenthood, but since the (((individualism))) movement started the sense of communal accountability has gone away and mothers do not pass down the skills needed to be able to make the home a safe and nurturing place for future children. If you look at data as simple as how many women feel that they can cook, these skills have been lost even with the plethora of information available immediately to people there are less and less who have the discipline to take it up. If completely healthy 30 year olds started dying in their sleep, people wouldn’t just write it off as something that just happens, and the police and medical professionals know this but it’s the mother’s testimony that they have to go off of.
