heya i havent personally done this but my mum went for adoption of a little boy she used to foster, we fostered him on permenant basis for bout 4 yrs and then at the last minute in the adoption process a family member of his came forward (after having no contact in the 4yrs) and because it was blood relation my mum lost the case
Altho its a long process its definatly worth it, the satisfaction of being able to give a child/ren something they cant have somewhere else. Very rewarding
