I've seen what she said and it is completely unworkable and actually, imo, is incredibly confused.
The notion is to give a child the notion that their response matters from an early age. But there's a huge problem here because there will be times, as a parent, where you have to ignore your child's blatant and insistent responsof non-consent.
Take my dd. From a newborn, she screamed her head off if she had to put her arms down sleeves. No matter how we approached it, she would scream and struggle. So as parents, we had to ignore it because newborns can't be partially naked in the depths of a northern winter. And we are always going to have to ignore it until she gets to an age where it doesn't matter so much if she gets cold and she has the verbal skills to tell us so.
So if we follow this advice, we have a paradox where a child's response matters (theoretically to set up a culture of consent), but then also a situation where that response, by default, will be ignored, thus teaching the child what?
The whole notion is nonsense; it negates itself in practice because parents, to be parents, have to override their children's responses in a whole range of situations.
