ABSTRACT
The wealth of experience, technique, and learning people found in the Bick observation method surprised and impressed them, further stimulating their curiosity and interest. Thus, since 1987, people have coordinated standard infant observation groups and developed applications of the method. By the late 1980s, after co-ordinating supervision groups using the standard Bick method and observing several mother–infant pairs during their first two years of life, Ruth Maltz and Nara Caron had gathered numerous ideas and questions about the initial human relationships, which fostered a desire and curiosity to understand these issues in the prenatal stage as well. The desire to know what is most secret and to decipher the enigmas from the hidden side of what is known has always fascinated mankind and has prompted the search for, and achievement of, important advances in scientific technology. Obstetric ultrasound emerged from this environment.
