For a half century, T Berry Brazelton has been listening to children and parents and to all those professionals who care for them. Now all those whom he has heard get to listen to him, and hear how his amazing career began and evolved. TBB's brilliance in listening to children started on the porch in Waco Texas, where he was enlisted to take care of his nine small cousins while the adults ate Sunday lunch. His skill at keeping them entertained and comforted led in surprising directions, including an offer from Broadway after his starring role in Princeton Triangle shows. He endured internship and residency in a medical world that did not listen, digressing to psychoanalytic training to deepen his skills, fought to reform the care of children in hospitals, and began the research into infant development that led to babies being seen in an entirely new light, and for which he is best known. Brazelton's exquisite observations and insight into newborn behavior led to the now international gold standard of infant assessment, the Brazelton Neonatal Assessment Scale. Such assessments in turn led to his research into individual differences in babies, and to both scholarly papers and popular writing, such as the beloved guide Infants and Mothers. Listening to distraught parents in his Cambridge practice led to his discovery of predictable patterns of regression and growth in infants and young children, underlying the whole Touchpoints theory and programs in over 50 sites in the US as well as his bestselling books. Not content to apply his ideas only to the care of middle class, comfortable families, Brazelton began advocating for all children, via Congressional testimony that led to the Family Leave Act,, books, TV shows, outreach to clinics in Harlem, tribal reservations in the Southwest, and consulting all over the world for governments and NGO's such as Unicef. In LEARNING TO LISTEN fans of Brazelton and all those interested in how children develop can follow both the roots of a brilliant career and the evolution of pediatrics and child raising in the 20th to the 21st century.
