This is my second marriage but first wedding. I want it to be really special and romantic. We plan to get married in my home. How would I include my son's girlfriend and my husband to be's daughter, because I only want my daughter as an attendant?

They could do a reading, pass out programs, greet guests, usher guests (if applicable), person the guest book, serve punch/coffee, light candles before the service, pin on corsages, cut and serve cake, etc. Include them in family pictures, have special seating for them at the wedding and reception, perhaps they could help decorate your house before the wedding, etc.
