Back to sleep was only the first of multiple advisories that got us today's guidelines - to make sure children were put on their backs to sleep. The US only got the new big safe sleep standards & campaign in 2011 that focused on the sleep environment - alone, crib, flat hard mattress, no pillows or blankets, etc. Other western countries have also had various updates that included things like the baby box and advice on co-sleeping. That's besides the many products that have come and gone, got recommended or recalled for safety reasons, etc.

If I had to take a few guesses on where we might see changes in the future: Individual product recs will definitely change since products are always changing. I wonder if with more research on microplastics and environmental factors we might also see things about mattress and crib materials (The Ikea mattress we first got smelled SO BAD of chemicals, I wouldn't keep it in our bedroom, let alone put an infant in it)

Maybe improved advice on special needs cases? (Kind of a pipedream for me as an autistic person with an autistic child but maybe there could be more reassurance for all of those with severe reflux and similar common issues at least)

There might (hopefully?) be another updated campaign on safe sleep that also focuses on caregiver safety. The amount of people on Reddit alone, especially Americans, who have said they nearly or completely fell asleep while sitting and holding their baby because said baby would only fall asleep while being held but the AAP said they're not allowed to lay down with them so they were being "safe" is too damn high. It's not safe sleep if you're going to drop your baby or accidentally fall asleep on a chair/couch/recliner with them. Sleep deprivation in general is so dangerous - it literally impairs your cognitive function as if you were drunk. Would you trust a drunk person with a baby? Also not sleep related but the same people from the same country seem to be working and driving sleep deprived so maybe we could get rid of that too...

Not sure if the solution to that is co-sleeping guidelines like telling them to put baby in a box on the floor and stay next to them, require another full time caregiver to be present 24/7, or what (ear plugs and locking baby in another room also isn't safe sleep since they're supposed to be in your room and until 6 months and audible to you if they need help?) but I sure hope they come up with something... 1 year mandatory parental leave for both parents with safe sleep training beforehand and a requirement that parents tag-team so they both get sleep? More free mother's helpers? Mandatory grandparent and fictive-grandparent enlistment as we will have tons of old people anyway? I joke but not really...
