Crash course in parenting - Life as a foster mom

But of course we wouldn't lie about it either, if they asked before then. Therapist said we ought to research bio dad and get as much information on him as possible.  Thus, I have been doing it. It's kind of hard to research someone with a common name. There are people who live in the same town with the same name, one even with the same middle init...
