Also, fostering is done differently in each province and state, so you might want to contact your local authorities about specifics. I know where I used to live that they would consider a family's experience with various medical or mental conditions when placing children, to give them the highest standard of care. It doesn't always happen that way, but it is a factor they consider. For instance, they wouldn't place a child in a wheelchair in my house with four floors and a gazillion stairs. It would be worth investigating, for sure.
