I have a 12yo daughter and I have allowed her to invite her BFF to the wedding and bachelorette party (we are going out for high tea). Daughter's friend's mom would like to join us for the bachelorette party and I would be more than happy to have her join us, should I also invite her (the mom) to the wedding and if I do, will I need to invite her husband and son also?? I dont know them, I have met the mom once and the daughter is being invited because is if my daughter's bff. what would you do? keep in mind we are having a very casual wedding at home with just our immediate families, if that makes a difference.
