"The hardest job I've ever had is being a mother."
"Through this haze, they must learn to be master interpreters of their child's behavior, reflexively using hypothetico-deductive reasoning to decipher the secret codes of their baby's cries, movements, facial expressions, connecting them to what had come just before and testing out their theories. Every mother is a Behavioral Scientist whose dissertation subject is her children, and who is regularly assessing the methodological errors in her "experiments." Her feelings of love are fueled by feelings of achievement, her own and her children's, as she remembers with each step all the tumbles that had preceded it. Only, her doctoral work is never complete, and a degree never awarded. Children are like the Borg on Star Trek; as soon as you've mastered one set of their behaviors, they shift to a new frequency, and the learning curve starts again. We may wait many years before we, and society, see some of the ultimate results of our work."
