Disorganized attachment (Disoriented attachment) refers to a relationship in which infants don’t seem to understand what’s happening when they are separated and later reunited with their mothers.

Babies' responses are particularly notable in the reunion sequence. In the other three (3) attachment patterns, infants appear to use a coherent strategy for managing the stress of the situation. The disorganized babies have no consistent strategy: They behave in contradictory, unpredictable ways that seem to convey feelings of extreme fear or utter confusion.
