The objective of the study is to determine the implementation of the recognition of individual tone of the baby by his parents and acoustic modulation of the baby based on parental response. The detailed study of the acoustic structure of crying and analysis of parental perception will determine the dynamics during the first weeks of life of this recognition, and the influence of factors such as parental presence, or breastfeeding .
