if I explain stuff to them whenever I can, on the occasions when I say “look, you’ll just have to trust me on this one”, they do actually accept it
I agree with this from @ZebraDanios and I think I do this too just naturally.
I've been catching up on this thread since being offline this evening and I think it's interesting. Lots of discussion about "the child's brain" and what a child is and isn't "developmentally ready" for.
The truth is that behavioural studies of children will always be hard to control for other factors like demographics etc. At the end of the day we don't know as much as we'd like about "the child's brain".
Employing empathy, instinct and common sense is the best we can do. Watching how our kids react. Seeing if the methods work. Then we know if our own individual child is developmentally ready for xyz.
If a suggested parenting method feels too outlandish, like a pp above mentioned about "wanky scripts" then it's a reasonable assumption that they won't work as well as more instinctive methods.
That's why, for example, I've never felt able to sleep train. Whenever I try, my instinct feels wrong.
But that's also why I can't be all smiley and "gentle hands!! I can see you're frustrated darling!!" if my dd snatches something (she never does this any more). Because my instinctive response is to show instant, though mild and still loving, disapproval, and my observation of her is that it works and doesn't harm her sense of self worth.
