and lukewarmness among children.
Even if the traditional Christian initiation for infants is adopted/restored in the West (Baptism, Chrismation, and Eucharist), what should be done by parents to catechize their children? Should there be a "coming-of-age" ceremony, with first confession and a special rite for Eucharist for children, so that they can renew their promises and show their rational acceptance of faith? This idea does not sound right, but I wouldn't be surprised if some were to advocate it.
What then? Those who do have their children initiated have a special responsibility to catechize their children well, and thus they have the burden to make sure that they themselves are properly catechized, rather than relying on others to catechize their children for them. Catechesis through the liturgy should probably be the primary way for doing this, and parents should explain the importance of a feast before Divine Liturgy, or after if necessary. They should be modelling prayer in the temple and at home. And if they do not have the requisite knowledge or prayer life to model for their children? Maybe they shouldn't have their children initiated, unless in danger of death.
