I can't answer your questions but just wanted to say that I think it's FANTASTIC that you're looking into this. I used to work for child protection and it just made me so sad how many kids were desperately in need of a loving stable home, whether it be for a little or a long while... and how few good foster homes were out there. From what I've read on here, you and Shell are wonderful parents and I think a foster kid would be really lucky to land on your doorstep. All the best for this journey.
