My fiancé is a single father and his daughter and I have become really close over the last two years. I knew from the beginning that if I wanted him, I had to take the whole package, and it was never an issue for me. Where he is, she is as well, and I wouldn't have it any other way. To acknowledge that, I want to take some time during the ceremony to not only make my vows as a wife to my future husband, but as a stepmother to my future stepdaughter. My idea was to surprise them both with this, and possibly present her with some token to represent that vow.
So, any ideas? What should I say to her? Should it be a surprise for them both or should I tell them what I'm thinking? Has anyone ever seen this done? And what to give her as a gift?
