Your job as a parent starts with insulating your kids from the consequences of their choices. Don’t put that in your mouth, don’t play at the top of the stairs, don’t touch the stove.
In time it shifts to helping them understand the relationship between the two — choices, and consequences — whether it’s telling the truth, doing their homework, driving safely in a storm.
It ends, for all of us, with accepting that relationship ourselves. They’re done when they’re done, whether you think they’re done or not.
If there’s anything harder, I have yet to encounter it.
