Mencius 4A.18: why the superior person does not
The issue is not education itself, but that in the closest relationship direct moral correction can quickly damage both teaching and the bond.
公孫丑曰:「君子之不教子,何也?」孟子曰:「勢不行也。教者必以正;以正不行,繼之以怒;繼之以怒,則反夷矣。『夫子教我以正;夫子未出於正也。』則是父子相夷也。父子相夷則惡矣。古者易子而教之,父子之間不責善,責善則離,離則不祥莫大焉。」
Gong Sun Chou said, 'Why is it that the superior man does not himself teach his son?' Mencius replied, 'The circumstances of the case forbid its being done. The teacher must inculcate what is correct. When he inculcates what is correct, and his lessons are not practised, he follows them up with being angry. When he follows them up with being angry, then, contrary to what should be, he is offended with his son. At the same time, the pupil says, 'My master inculcates on me what is correct, and he himself does not proceed in a correct path." The result of this is, that father and son are offended with each other. When father and son come to be offended with each other, the case is evil. The ancients exchanged sons, and one taught the son of another. Between father and son, there should be no reproving admonitions to what is good. Such reproofs lead to alienation, and than alienation there is nothing more inauspicious.'

Central question
Why does Mencius say that the superior person does not directly teach his own son?
Direct answer
Because the father-son bond is so near that direct moral correction easily slides from rectification into anger. Then the child is not truly taught, and the father too is dragged into the conflict, leaving both relationship and instruction damaged.
First principle
The most important relationship is not always the right vessel for the most direct correction. When the relationship itself is more basic than the corrective act, preserving the bond may be the condition of long-term education.

Citation note
Do not read it as permission for parents to abandon formation. Mencius is not cancelling education, but rerouting it so that intimate bonds are not burned down by direct blame.
