This study was a prospective, randomized controlled trial. The study sample consisted of 105 healthy neonates who conformed to the case selection criteria. Neonates were randomly assigned to the following groups: swaddling (S), maternal holding (MH), and controls (C). The study data were obtained using an information form and the Neonatal Infant…

Kangaroo care (KC) or kangaroo mother care (KMC), sometimes called skin-to-skin contact, is a technique of newborn care where babies are kept chest-to-chest and skin-to-skin with a parent. The research was carried out experimentally to investigate the effect of the early kangaroo care by using Neonatal Comfort Behavior Scale in invasive…

The behavior of newborns is ambiguous. Cultural models--representations shared by members of a community--provide new parents and others with a cognitive and motivational structure to understand them. This study asks members of several cultural groups (total n = 100) to judge the "similarity" of behavioral items in the Neonatal…

Newborn infants preferentially orient to familiar over unfamiliar speech sounds. They are also better at remembering unfamiliar speech sounds for short periods of time if learning and retention occur after a feed than before. It is unknown whether short-term memory for speech is enhanced when the sound is familiar (versus unfamiliar) and, if so,…

Objectives: Infant crying is particularly frustrating to caregivers in the first few months of life and the most common trigger for shaking and abuse. The effectiveness of the "Period of PURPLE Crying" prevention materials (DVD and booklet) designed to increase knowledge and change behaviors related to crying and the dangers of shaking…

This article reports the behavior of 3 newborn chimpanzees in the first 4 months of life, reared by their mothers and living in a community of 14 chimpanzees in a semi-natural enriched environment. We focused on spontaneous activity during the night partly because sleeping behavior constitutes an essential part of the infants' activity.…

Newborn infants showing anthropometric signs of atypical patterns of fetal growth were compared with infants of appropriate growth on the Neonatal Behavioral Assessment Scale and on recently developed supplementary items. The sample consisted of lower-socioeconomic-status families in San Juan, Puerto Rico, and included teenage and older mothers.…

Examines the relation between aspects of the fundamental frequency (basic pitch) of 16 infant newborn cries and 28 multiparous mothers' perceptions of those cries. Results support the hypothesis that increases in fundamental frequency are related to increases in maternal perceptions of the intensity of the infant's cry. (Author/RWB)

Two studies were conducted to examine (1) 1- to 3-day-old infants' imitation of their mothers, and (2) mothers' imitation of their newborn infants. For the infant imitation study, 30 mothers and their infants served as subjects. Two observers stood behind the mother to view the infant's face while the mother presented one of the following…

This paper reviews a few studies, both in animals and humans, that are relevant in helping us to understand factors affecting infant-mother interaction. (MM)

Evaluates the effects of continuous lumbar epidural anesthesia on the newborn and on the developing mother- infant relationship. (Author/MP)

Assessed behavioral and physiological differences between 61 breast-fed and 39 bottle-fed neonates. Mean postpartum assessment occurred at 37 hours. Results suggest that breast-fed infants had significantly longer heart periods, elevated heart period variability, and higher vagal tone than bottle-fed infants. (Author/RWB)

The infants of the adolescent mothers were found to be significantly less capable of responding to social stimuli, to be less alert, and to be less able to control motor behavior and to perform integrated motor activities than were the infants of older mothers. Journal availability: J. B. Lippincott Co., E. Washington Sq., Philadelphia, PA 19105.…

Links between neonatal biological rhythms and the emergence of interaction rhythms were examined in 3 groups (N=71): high-risk preterms (HR; birth weight less than 1,000 g), low-risk preterms (LR; birth weight=1,700-1,850 g), and full-term (FT) infants. Once a week for premature infants and on the 2nd day for FT infants, sleep-wake cyclicity was…
