My mom actually said the same thing with my first, but she was there from beginning to end. Your mom will come around because she's not going to want you to go through that alone. It's a an experience she wouldn't miss for the world! She's just nervous also. And idk if I would be comfortable with a,student delivering my baby, that's kinda scary.
I know how you feel my bf decided to go to the Army and may be gon to basic training around my delivery time I wanted him to be in the delivery room and my mom but now he may not be there and my mom is saying she doesn't want to be there b/c she won't be able to take it b/c her baby is having a baby so I'm going to be alone during my first pregnancy which is scary altogether im not which doctor will be there delivering my baby b/c the clinic I go to trains students to delivery babies and so far I've seen 3 different doctors its just a lot
