re: Granting dying wishes vs going against a parents wishes.

While I would respect her because she is old and on her death bed, it would bother me. You and your wife made a decision about your kids and your dying grandmother (the kids great grandmother) wants YOU to do what she think is best for them.

Would she find out if you told her yall did it but didn't really do it?

In order to get them baptized Catholic don't you have to go through classes and other stuff before doing it? I know if an adult decides to become Catholic they have to go through stuff... But that seems like an odd thing for a great grandmother to want from her great grandkids.
