He never requests. But he always notices. And later in the sandbox, I sometimes overhear him describe his own birth parents or how he was born, and if I don't detect pride, I at least know that he has his own story and is discovering how he feels about it. I'll keep in touch for the birth mother's sake, but I don't want to confuse my child. If the parent feels confused about contact with the birth parents, then the children will certainly pick up on those feelings.
Adoption is confusing - our children have two sets of parents and two heritages.
We cannot protect our children from this confusion, but we can give them the skills to deal with all of the complicated realities of being adopted. They will understand information presented in a simple, straight-forward manner. Maintaining contact with the child's birth family should be for the child's sake. We focus on our child's birth country, so he will feel connected. It is important for us as adoptive parents to look at our motivation.
