so my mother, MIL and FH all agree it's ok to include on the save the date "an evening for adults" or "adult reception." There are a couple people who have children and we want to let them know ahead of time. I picked save the dates with a front and back side. The front with our engagement photo and wedding date. The backside will have the reception location, note for formal invitation to follow and our wedding website URL. I keep hearing to exclude information about not having kids and to address the envelope to Mr and Mrs XYZ and they would figure it out by word of mouth as well. I think word of mouth is worse and as the bride and groom we should note something to our guests. Any ideas on what to do? I could be overthinking this. I want to stay away from hurting anyone's feelings since all these children are my FH nieces/nephews.
