Hi P.~
I can totally relate!! My daughter, also Sofia, had to be baptized with catholic Godparents. we basically had to take whoever was available because we didn't have to many to choose from. our church is very strict so both mother and father had to be PRACTICING, needed papers from their parish. it was a lot to go through. another option u have is to technically not have GP's. She can be baptized by the parents, and not have GP's.
Right now i am NOT happy with my daughters Godparents, they never see her, didn't go to her first bday, etc. the 2 ppl that we wanted to be the GP's couldn't because they are not practicing and could not obtain papers.
i know it probably means a lot to your sister, but i'm sure she'll understand that there's just nothing u can do. i think at this point, the most important thing is that you daughter is baptized in God's house. God parent is just a title, and anyone can obtain a title, but by their actions and how involved they are with the child is truly important.
my best friend is more involve with and visits my daughter than her Godmother.
i wouldn't get too stressed about it. just explain to your sister, maybe do a little private ceremony amongst yourselves making her the Godmother.
i hope this helped. Best of luck.
