hmmm, quotegarden's my crutch. only thing i thought of was the bible verse:
Train a child in the way he should go, and when he is old he will not turn from it. Proverbs 22:6
and of course there are a million translations you might like better at biblegateway.com...
Point your kids in the right direction-- when they're old they won't be lost.
Teach your children to choose the right path, and when they are older, they will remain upon it.
etc, etc, etc... hth. Ü
