William Sears came to the term "attachment parenting" in 1982 by reading Liedloff.[7] Initially, he referred to his new philosophy as "the new continuum concept" and "immersion mothering".[8] When he published his book Creative Parenting in 1982, the concept was largely elaborate already. The "7 Baby-Bs" were not explicitly presented as a canon yet, but as basic elements of a new parenting philosophy they were distinctly clear even at that early point.[9] In 1985, William Sears and his wife Martha Sears began to link the concept – ex post – with attachment theory which they had begun to recognize at that time.[10] From then on, they used the term "attachment parenting".[11]
