I'm not really lecturing you, you know. I wouldn't presume.
Ten years of parenting have taught me that it is not possible to force a child to become enriched. They aren't like wheat, you know? You can lead a girl to Latin and you can make her conjugate for hours, but you cannot force her to love Virgil. You can lead a boy to the piano and you can make him practice, but you cannot force him to have a heart for music. You can even lead a child to the twelve times table and you can make her memorize it; you can make her rattle it off like a trained monkey to the amazement of all your friends; but you absolutely cannot force her to grasp that numbers are never cruel, but always clever and often amusing. And so it goes.
What do you mean you don't want to play with the pluperfect subjunctive?
However, hope springs eternal! One of perhaps two things the mavens of child psychology have gotten right is the practice of providing children with enriched environments. There is no real need to force a child to want what is beautiful. A child is a man, and thus the apex of beauty. Give him beauty and he can be trusted to absorb it into his being by sheer accident. I have found this to be doubly the case when a child’s life is filled with what is genuinely, objectively beautiful over and above those things that are educational, manipulative, and loud. If, however, you would like to ensure that your children lose as many their rough edges as they sanely may, there is one thing above all others that you need to do: be enriched yourself.
If you want your kid to love reading the Aeneid in the language of Virgil, take up Latin yourself. If you want your kid to love practicing his arpeggios, take up the piano yourself. If you want your children to feel comfortable around numbers, don’t be shy about what you don’t know; rather, become reacquainted with mathematics and discover again how charming it can be. Learn before your children, with them, and after them all the things you want them to learn, especially when they are little. Let them see you struggling to become a more beautiful person, and they will seek to join you in the struggle simply because that is how love works.
Work with them instead of on them, and you'll both be happier. Then the day will come when they surpass you, which is really what you wanted all along.
