Can you give examples of what you are talking about? I’m interested in your view and think I agree, I’m just not sure of what exactly you mean necessarily.
It all started for me when I was debating shelling out for a course of Baby music and sign classes type thing. I decided that although all the websites about it stated the huge benefits to babies I was interested enough to see what was supporting these claims.
After a lot of internet rabbit holing I found some actual studies. Suffice to say it was extremely underwhelming but you could see how huge claims and leaps had been made and then just quoted as sources from other websites, with almost no link back to the research.
Same goes for all things "attachment". So completely misunderstood and bandied around. Baby led weaning is very trendy - and very light on actual evidence. Co sleeping - hot potato and yet bizarrely in this case the evidence is real, and the parenting websites dispute it(?)
Breastfeeding benefits are hugely over hyped, although I fully support it, I wanted the facts. The book "Cribsheet" was a revelation for me. Was recently interested to get to the bottom of claims that breast milk composition changes when babies are ill, because I thought it was interesting. After a lot of leg work I found the study the claims came from. As with most of this stuff the study ended on the phrase "initial findings indicate XXX but requires further study". Headlines always leave out the crucial last bit of that sentence it seems
Now wondering where the evidence for "gentle parenting" came from. Most of this stuff is anecdotal yet is taken as fact so I suspect the same.
These are just some examples, Im back to work now so my boring debunking hobby isn't getting so much time
