Guess you don't have kids yet!

Meeep, wrong. My child is older than 18 months and doesn't "deceive" me. How could they lie, if they still try to figure out that whole language business? I'm not "telling them off", though, so maybe they don't develop some kind of weird mitigation strategy.

That whole narrative reeks of that "babies are tyrants that need to be taught how to be proper people" bullshit.

And asking parents about the behaviour of their children is anything, but proper developmental science.
