Sensitivity (attachment theory)

A sensitive mother is able to see things from the baby‚was point-of-view. She is alert to perceive her baby‚was signals, interprets them accurately, and responds appropriately and promptly, unless no response is most appropriate. She tends to give the baby what he seems to want, and when she does not she is tactful in acknowledging his communication. Furthermore, she makes her responses temporarily contingent upon the baby‚was signals.
