My novus ordo parish church demands parental education for the baptism of every single child a couple has, even if they and their children are at Mass every Sunday. The classes are taught by ignorant lay people, the classes are few and far between, and they have delayed infant baptism by as much as three months. In my opinion, it’s a moral crime to delay infant baptism for so long.

If so, it does seem to be an imposition and a maddening aggravation. And if it gets on to long delays like 3 months, that's a real offense against the sacrament.
I'm thinking if my husband and I were in that situation, the best tactic might be to go to one of these classes sometime during the course of the pregnancy (you do have a nine-month window of opportunity there) so the baby could still be baptized within days of birth.
And use the class to raise your hand, make additions or corrections to the ignorant catechist's presentation, and use the whole thing as a grand opportunity to do a little remedial catechesis.
If you do it assertively enough, they may waive the requirement that you come back for Babies #2, 3, and 4!
