Let’s delve into DMC 24, where a previous question was asked about lay preaching.
24. Since the eucharist is always the action of the entire ecclesial community, the participation of at least some adults is desirable. These should be present not as monitors but as participants, praying with the children and helping them to the extent necessary.
Again, school Masses seem the usual scenario for these prescriptions. Rarely have I seen a teacher or catechist not engaged in prayer, but adults with younger children are always ready to assist.
With the consent of the pastor or rector of the church, one of the adults may speak to the children after the gospel, especially if the priest finds it difficult to adapt himself to the mentality of children. In this matter the norms soon to be issued by the Congregation for the Clergy should be observed.
Those same norms would probably not be issued today, nor would CCC 766-767 be as liberally interpreted as in the past. Some would say, and I could not argue against it, that by not attending to the training of seminarians in preaching the children, the curia has abandoned its role somewhat in this regard.
Even in Masses with children attention is to be paid to the diversity of ministries so that the Mass may stand out clearly as the celebration of the community. [See Sacrosanctum Concilium 28.] For example, readers and cantors, whether children or adults, should be employed. In this way a variety of voices will keep the children from becoming bored.
A common sense point. Any comments?
