My DH and I are invited to attend a gender reveal/jack-and-Jill type shower. Or something like that. I really don’t know. The couple wants to announce the gender of the baby and have a bit of a get-together for all their friends and family. They have asked that everybody bring diapers, but made no reference to a registry or gifts or anything. Part of me wants to be safe and bring a gift, but the bitter, infertile side of me says no. Has anyone ever attended something like this? Any suggestions?
