What if you get it done and she hates it? You can't reverse it. I think it's like any other enhancing surgery - wait until she is old enough to decide what she wants to do with her body. They are her ears after all. Maybe suggets to your DH that it is your job as parents to love her just the way she is and help her also love herself in that way. IF she has an issue with her ear when she gets older then start to discuss the prospect of surgery. I personally don't think it is your job as parents to protect her from the world but to teach her and enable her to deal with the world in her own way.
