I wonder what the long-term effects of the "put them to sleep on their back" advice will be, though. Our son hated (and continues to hate) sleeping on his back. We put him down that way because that's what medical advice recommends today, and if he died of SIDS because we didn't we'd feel terrible. But as soon as he learned to roll over, the first thing he did was start sleeping with his butt up in the air. I'm told this is very common, and most infants don't like to sleep on their back, and will avoid it if possible. Are we going to find out in 20 years that we've raised a generation of kids with lower cognitive abilities and poorer emotional control because they didn't sleep well when they were newborns? That they have asthma and sinus problems from mucus dripping down their throat while asleep? That there's some other unknown risk factor we're not accounting for? That's certainly the case with a lot of common parenting wisdom from the 80s. Oftentimes both sides of Chesterton's fence suck, but they suck for different reasons. And humans have a bias toward fixing problems they see, not being grateful for problems that were silently averted. That's why we perpetually tear down fences and generate new stocks of problems.
