     In the past decade, openness has become mainstream, and the vast majority of domestic adoptions

(家庭领养) are open ones. Even so, potential adoptive parents and birthparents are often fearful when

they first hear of the concept.

     Making Room in Our Hearls: Keeping Family Ties Through Open Addption answers the most

common questions about the influence of open adoption, and how it affects the lives of everyone related.

Duxbury, a family expert who specializes in adoption advice, is also an adoptive parent. Her book opens with her own family's story.

     Duxbury surveyed 150 families, but her book is not a collection of data. Instead, it allows these

families to share their thoughts and wisdom, their joy and pain; the stories communicate the great

happiness families feel at" working together for the sake of the child" and the steady view that the

adoptive parents are the parents. They also touch on problems that can arise from opening closed

adoptions.

     The most convincing advocates for open adoption here are the adopted teens themselves.

Commenting on the question people always ask: "Are you confused about who is you real

mother?", Josh, age 2l now. states, "Kids aren't stupid. I think I would be confused if my birthmother

was not in my life. But my birthmother is not another parent. Your parents are your parents. My

birthmother is really important to me. She is like a special aunt, but she is not my parent."

     "Openness gives children the gift of possibilities, for now and for the future," writes adoption expert

Patricia Martinez Dorner in her closing thoughts. "It is not a ctre-all, but it creates the possibility for a

stronger sense of permanence and identity." This book is important reading for everyone touched by

adoption.
