So here's how the first visit went down!
I picked Alex up from school and drove him downtown to drop him off with the County DHS worker around 2pm. The night before, Alex and I went around the house and took pictures of his room and toys, and a picture of him with the dog to show his mom. I wrote her a short note letting her know how great he has been and how he is doing in school.
When I dropped him off I asked the DHS worker to please explain to Alex that his mom was in prison on the ride over there, he believes she is at "Sleep Away Camp".
Around 6pm DHS worker brought him back to my house. He told me that he didn't need to say anything to Alex because it was "clear where they were at" so clearly Alex understood. Needless to say Alex does not understand, he now things mom is at a "very bad school" and she should have picked a better school to go to!!!!! AHHHHH!!! I'm letting it go for now, but will probably have the conversation with him before the next visit. DHS worker said mom was very appreciative for the letter and pictures and extremely emotional. I think (hope) it was clear that he is in a good home, which I know has been an ongoing concern for his birth family. His previous kinship home would frequently tell him they would send him to a bad foster home if he didn't behave. She asked for me to get a specific lotion for him, which we have since done. You can tell he really likes putting on the lotion that his mom wants him to use and it gives him a connection to her. We really haven't had any behavior issues due to the visit. We still have a lot of faux illnesses going on, but its been that way since he came so its not related to the visit itself. No word on when another visit will take place.
