As an adoptive mother, I am thrilled to hear that your DH's office is doing this! I was very sad when I brought DD home, and didn't get any of the "normal" family/friends experiences of bringing a child into our home. My sister came over and helped me set up the bedroom. Two friends brought me "welcome home" gifts/cards. But no one really asked to see pictures, asked how it was going, offered to throw a meet-and-greet, or anything. I already felt like such a failure--infertility, family that couldn't take care of their own child meaning she ended up in foster care, then having to "prove" that I was a fit parent by very virtue of trying to bring her into my home--and not having any of the normal experiences just heightened that awareness that adoption isn't seen as the "normal" way to bring a child home... Sorry, off my soapbox now!
Others have brought up great wording for this!
