Maternal Humming during Kangaroo Care: Effects on Preterm Dyads' Physiological Parameters.

Humming is probably more effective than speech for improving mothers' cardiorespiratory function and infants' self-regulation. We intend to understand the effects of (1) maternal humming vs. speech on preterm infants' physiological parameters, (2) maternal humming vs.

Maternal perception of infant's intersubjectivity: a questionnaire.

Introduction: Intersubjectivity is a fundamental dimension of the mother-infant relationship.

Objective: Design of a questionnaire to assess maternal perception of the infant's intersubjectivity.

Design: After running a focus group with mothers of infants within their first year of life, items related to maternal perception of the infant's intersubjectivity were generated.

Vocal responsiveness of preterm infants to maternal infant-directed speaking and singing during skin-to-skin contact (Kangaroo Care) in the NICU.

Unlabelled: Vocalizations of full-term newborns occur in a short latency time during the neonatal period. Contingent response time of preterm babies is still unknown. An increase of preterm babies' vocalizations following exposure to parental speech was also observed.
