Big hugs!

I know I struggled a lot with people who really don't understand the emotions of foster care and/or adoption and had to really struggle to put their insensitive comments to the side, but there are several people that I lost a lot of respect for going through our process. It's one of those forgive, but not forget things. You are in no way stupid for being attached - it is completely expected and you have to cut yourself some slack - this is your first experience. Not knowing what to expect, the fact that it happened so fast - all of that is making these emotions even harder to grasp. I remember in our MAPPS class we talked a lot about how even an infant has trust/attachment issues if they aren't placed in a loving environment right away. It was really eye opening to hear some of the real-life stories, where some of the kids adopted out of foster care had no obvious "issues", but couldn't attach because they had never bonded with anyone immediately after birth. It's really powerful stuff, and what you are doing is providing her that comfort to help make her a better person.
Definitely check and see if there are support groups available - we didn't use that and I really wish we had - I think it would have made it easier to have a group of been there/done that types that could help use their experiences as examples. My best advice is to keep asking questions until you get some sort of answer. We had problems with our social worker not giving us all the informaiton, but the kids social worker was much more approachable, so we actually went to her with a lot of questions. I struggled with it being so intimidating to ask questions because you don't want to ask the wrong thing or protray anything about yourself in a negative light. I felt like our social worker expected us to just "know" things and not ask her and got frustrated if we asked too many questions. But the most important lesson I learned is to advocate for yourself and for that little girl!
I think the pictures is a wonderful idea! If nothing else, the social worker can hold on to them in her file and put them in a life book as she grows up. We got life books when we adopted M and K and they only had a handful of pictures from the 2 years they were in foster care and nothing from when they were babies. We don't know if the biological family has any, but I think the pictures would be a great thing for her to have as she gets older.
Hang in there - hopefully the social worker will call you back today. You ARE doing a GREAT job!
