Wedding Etiquette. . .have a question

Thanks everyone for the thoughtful insights/advice. I do think that this bothers my friend more than it will her new husband. I don't think she ever expected her husband to walk her daughter down the aisle or do the father/daughter dance. She understands this is the role of the natural father. But I think she was looking for some recognition beyond that of her current husband. But I guess if you acknowledge the step dad, you also have to acknowledge the step mom so perhaps her daughter is keeping it simple, which is best.

Thanks again for the insight. I will share it with my friend and hopefully it will sit better with her.
