The "agency" that is dominated by the influence of their peers, schooling, and media you allow them to consume as impressionable and innocent individuals.

Normally I'd say let them grow, have their own agency and learn the world in their own eyes with parental supervision. But right now, the media and culture are so highly toxic and degenerate, that I say it's our duty as parents (and humans) to shield them from that, and instilling positive values.
