When my daughter winged and my son winged, it was really meaningful for me to pin on my original set of wings. At the time(s), however, they were both single. Had either one been married and wanted a spouse to pin on the wings, it would have been fine with me.
As an easy compromise, have the spouse pin on the dad's original set of wings. Covers all the bases.
Daughter and son winged....you da man!
