I am reading this forum and I am so thankful that for the most part kinship adoption / fostering does work.However have any of you experienced it not working? As I said before I have a family member I am thinking of taking,however the mother is addicted to drugs,all of the other members are also not a resource.They love to fight and keep drama amongst each other and I really don't know them well because of their lifestyle.
I already have 4 children of my own although I am a registered foster parent.
It scares me because this is my family and I feel obligated to them,but they are not nice people for lack of a better word so I am thinking to leave the situation alone and wait for a non relation foster care placement.
I am torn because I want to and I don't. I know taking these children will overwhelm me because they need counsoling, therapy and the agency would require me to do so many hours of additional training and classes not to mention it will make me associate with the part of my family who I know will cause me problems.
There is also a question of neglecting my own children to take care of these who need so much care.I would hate to move these children from a foster home only to find out I cannot do it and have them moved back into the system. That would really make my family mad at me.Some are mad at me because I want to and say I should mind my own business others are mad say I need to step in and do something. But for some reason I think it wont work and it has me really torn up.
Is there any feedback on situations when it did not work and how did you feel?
