I have a question that I cant seem to find a pre-filled answer for. I'm hoping you guys can help me. One of my bridesmaids is single but I want to extend the option for her to bring a guest. I also want her to know that her 6 yr old son is welcome. How do I address her save the date and invitation? Obviously I can explain it in person but I don't want her to get the wrong idea when opening her mail. Any suggestions?
