Every adoptive family needs a copy of Parenting the Hurt Child by Gregory Keck and Regina Kupecky. Even if you think your adoption situation was idyllic, adoption by definition involves a loss for the child at its center.
I love this book because the authors treat adoptive parents with such respect; they are viewed as the only parties who have the power to bring healing to the child by teaching him to attach to them. A therapist can help, but the job belongs to the parents. It's full of lots of practical instruction on fostering attachment--things that are fun and doable, and great for keeping *any* child firmly attached (hello teenagers!).
And they view home-schooling as a non-issue, a refreshing change for child welfare professionals.
I'm giving this book a whole-hearted endorsement.
