Just finished reading Talking with Young Children about Adoption. I've had adopted children for 9 years now and still found it helpful. I've also bought Telling the Truth to your adopted or foster child but haven't read it yet - it looks like it tackles harder issues prostition, drugs, physical abuse etc.

We have contact with all three of our children's birth families and it is wonderful. We are fortunate everyone is very open and the children have greatly benefited. Due to the families being os (intercountry adoption) we only see them every 2 years but we write, email and phone often.
