Which theorist proposed that the characteristics of oldest and youngest children are complementary?

The theorist who proposed that the characteristics of oldest and youngest children are complementary is Toman. His work focused on family roles and dynamics, particularly how the birth order can influence personality development. Toman suggested that the oldest child often assumes leadership, responsibility, and conformity, while the youngest child tends to be more free-spirited, creative, and attention-seeking. This complementary dynamic fosters a balance within the family system, where each child’s traits can offset and support the others, creating a more harmonious family structure.

Understanding this theory can help therapists recognize and address family dynamics as influenced by birth order in their practice, allowing for better insights into client relationships and behaviors.
