Leo is now 8 years old. Since the age of 9 months, he has lived in four different temporary foster care arrangements. A family is preparing to welcome Leo into a long-term guardianship placement, but they are concerned about his ability to build a secure bond with them. They are also worried about his behavior and performance at school. His recent progress report notes that Leo frequently acts out in class, has been involved in physical altercations with classmates, and is currently performing well below age-related expectations in his core academic assessments.
