Which theorist suggested that children could form multiple attachments?

The correct answer is based on the contributions of Schaffer, who conducted research on attachment in children. Schaffer proposed that children could form multiple attachments, which is an essential part of their social development. His study highlighted that while infants typically have a primary attachment figure, they are capable of forming additional attachments to other caregivers, such as parents, grandparents, and siblings, providing them with a supportive network.

Bowlby, while significant for his attachment theory, primarily emphasized the importance of a primary attachment figure and the bond between a child and their caregiver. Rutter's work focused more on the effects of separation and the stability of attachments, rather than the formation of multiple attachments. Malaguzzi, known for the Reggio Emilia approach, emphasizes child-centered learning and the environment, but does not concentrate specifically on attachment theories. Thus, Schaffer's research directly addresses the concept of multiple attachments in early development, making it the most relevant choice.
