God bless the grandmas, aunts, grandpas and others who register the kids for CCD, bring them in, attend parent meetings, bake cookies, help kids learn their prayers, take them to Mass etc. Without them the faith would not be passed on to many of these children. By all means, follow the suggestions above. You have already fulfilled your responsibility in raising your daughter, what she does about it is on her conscience, but her kids will pay the price.
Canon law is very specific that parents must present their child for baptism as soon as possible after birth, and it is the parents’ responsibility to educate their children in the faith. CCD is a program (one of many) parishes adopt to assist parents in that task.
I hope your daughter does not find out the hard way, as I did, the heavy price you pay for putting your job ahead of your family’s spiritual needs and your own practice and knowledge of your faith.
