A LOT.

But how would a child understand? Is there no cheat code for this?

Genuine question… A boy wants to drink the oreo shake in parent’s hand. He asks for it. The parent says no. The boy asks why. What should parent say? Now, I understand that there could be multiple reasons, like sugar being bad for health and being kind of addictive. But whatever reason they give, would it not be implied on the parent themselves?

Like, how should parent handle this? This is just an example situation, but I would really like to know more.
