when we were growing up we lived with a kid who was not our biological sister we really loved her
Was she a foster? What topic?
yes she was, a distant relative from my mum side
I think we need more information from the left menu. Did you deal with the foster system or go through the adoption process? It is nice that she had your family.
my parents did a foster system they were their foster parents
That is great. Do you or any of your family foster or plan to foster yourselves? A safe place to grow can make a huge difference for someone.
for now we have no plans for that maybe in future,  i agree with you a safe place can make a difference
I wonder when the foster care system began to help connect children with families? 
the foster system can help since the families of these children are mostly known so it becomes a bit easy but if all policies are put in place.
Do you feel the screening process and follow up was thorough or different because of the familial ties?
