"The good enough mother, owing to her deep empathy with her infant, reflects in her face his feelings; this is why he sees himselfin her face as if in a mirror and finds himself as he sees himself in her. The not good enough mother fails to reflect the infant's feelings in her face because she is too preoccupied with her own concerns, such as her worries over whether she is doing right by her child, her anxiety that she might fail him."
