I just realized I never did post an update after we finalized C's adoption.
It did happen in late February, we have pictures with the judge, her name was legally changed and we are just waiting for the state to send us an updated birth certificate so we can finalize all the paperwork. (I'm hoping the attorney will manage to "accidentally" get us a copy of the original birth certificate again, too.)
The home is officially closed -- I have no more bedrooms! -- but we have asked to be notified if there is another biological sibling. Birth mom is incarcerated (and has been for about 4 months), so I'm assuming we're safe from that all for a little while. I asked the caseworker, somewhat jokingly, if there was any news of another pregnancy already; she said she sure hoped not. I'm crossing my fingers that the jail would tell DFCS if they had a pregnant prisoner with a history with CPS, so that means she's probably not pregnant right now. I really have no idea what we'll do if we get that phone call; agency caseworker said (if birth mom was pregnant already), she would go ahead and decline the placement on our behalf to save us from ourselves. We'd still want to know of the child's existence, even if we couldn't take the placement, and hope to be able to set up contact if another baby ended up adopted. But that's all a bridge to cross when we get there.
Mr D and I went away for a weekend recently -- our annual just-us trip -- and noticed that "five" is apparently the number that makes people say "wow!" when asked how many kids we have. We heard it almost every time; that happened rarely when we used to say "four." I can't imagine what people would say if we ever start saying "six." (There I go again. I will not think about another sibling, I will not think about another sibling. I will not think about another sibling!)
It's nice to be down to normal business -- no more caseworker visits, no more documenting medications, no more asking for copies of visit notes from the doctor -- and I have a little less of the time-on-my-hands feeling that I had after Lucy's adoption finalized. A busy 2 year old and a baby starting to crawl will keep me quite well occupied, thank you very much. Also, there were never family visits for C, so that was one less thing that went away, so to speak.
It's a little strange to be thinking about colleges and preschools at the same time, but the age gap is really what makes this doable for me. I can't imagine having added two little ones when my original crew were younger and less self-sufficient.
