That’s because they were CHILDREN, the point was not the sin, the point was the practice of going to Confession, like the Practice of going to Church, it’s to make it a lifetime habit. To make it second nature. At some point they are supposed to learn the faith as an adult and approach it as an adult.
*They* who?
The people who made up sin to confess to a priest?
They didn’t just do it only when they were children.
What a system of bondage. Doing something weekly to get into the habit of it? So you can do it the rest of your life as second nature. At that point, you can do it without even thinking. It loses all it’s meaning when you can do something so by rote that becomes nothing more than going through the motions. Where’s the relationship in that?
And what’s wrong with just keeping short accounts with God and going directly to HIM whenever we slip up and dealing with it right away?
That could also be called brainwashing and conditioning or “grooming” a child very early ....like Islamists do with thier children by teaching them habits without understanding why or about what they are doing them for.... “habits’” then become ingrained as a foundation to build all the other “stuff” on which entraps them.
