In the report, we use the language of parents bonding with their children and children attaching to their parents—that's how psychologists refer to it—and how bonding to a child certainly can be easier if they're attaching to you.
If they express no attachment or unhealthy attachment, it can be very difficult. It poses added challenges. All of us who are parents know that parenting can be challenging, but when you have a child who's not attached to you, it's very difficult.
I had an experience. I adopted, and a friend of mine adopted at the same time. Her child had a very unhealthy attachment style and would come to me as often as to my friend whenever that child needed something. He was treating me as much as his parent as her. I can't imagine the difficulty she found in that kind of behaviour. It was sad for everyone, for him and for her. He definitely got over that. He's doing really well now, but that's challenging.
