The questions to think about might be:
in thinking about the worst possible scenario that could happen (i.e. child has RAD or other serious emotional issues) -
- do you have good support networks - both to offer you help with the child (respite for yourself) and one also for your own mental health? Not only counselors/therapist/psychiatrists but family & friends who will be there for you when the going gets rough and alone. Don't underestimate the importance of this!
- do you work - would your employer be willing to let you have time off for appointments or if you need to be at home with the child?
a good website:
Older Child Adoption is undergoi. (I just checked and she's actually updating her site right now) Susan is a single mom who adopted a child (who was six at adoption) from Russia.
good luck!
