The aim of this study was to determine the effect of sleep quality of postpartum women on perception of insufficient milk and attitude to breastfeeding. The research was designed as a cross-sectional study. It was carried out with 347 mothers in a university hospital between December 2021 and July 2022. Data was collected via a personal…

This study has been conducted to examine the relationship levels of fathers who have 6- to 12-month-old babies with their fathers, and their attachment status with their babies. The sample group consisted of 313 fathers. Fatherhood Scale and Father-Infant Attachment Scale have been applied to the fathers who participated in our study,…

This study aimed to identify whether appetitive traits predict exclusive breastfeeding (EBF) duration for the first 6 months of life and to assess other predictors of its duration. 186 six- month-old term infants were included. Appetitive traits were assessed at 3-4 months of age. EBF duration, feeding practices, sex, maternal age and education,…

The development of copying behaviours of a group of infants from 9 to 15 months of age is analysed. These behaviours are classified according to their type (mimetic or imitated) and function (instrumental, social or hybrid). The function of the behaviours is derived from observable indicators linked to dyadic interaction. Mimetic behaviours are…

Maternal input addressed to children after an early hospitalization (EH) was longitudinally compared to maternal input directed to typically developing children (TD), at 6, 9, 12, 18 and 24 months of age. The data were analyzed with the CHILDES tools for (a) word-tokens (b) word-types (c) Mean Length of Utterances (MLU) and (d) questions in which…

This study used an ethological approach to explore the behavioural adaptation of nineteen infants during their first six weeks in Residential Care (RC), or a Foster Family (FF) or an Infant-Mother Centre (IMC). Direct observations were conducted once a week at bath time. Observed behaviours were: sleep-wake states, visual exploration, motor…

This study used an ethological approach to explore the baby-caregiver dyadic exchanges (Attempted interactions, Triggers, Interactions) of nineteen infants during their first weeks in Residential Care (RC), or a Foster Family (FF) or an Infant-Mother Centre (IMC). Direct observations were conducted at feeding time. Observed behaviours were: baby…

This research study recruited 107 fathers from the United States (n = 31), Taiwan (n = 36), and Thailand (n = 37) to examine fathers' involvement in daily caregiving and engagement tasks, as well as fathers' accessibility to their infant(s) during weekdays and the weekend. Results indicated that the most influential demographic variables on father…

Caregivers' sensitive responses to infant cry have long-term consequences for adaptive child development. Although mounting evidence suggests that parents who experience high emotionality to infant cry respond less sensitively to infant cry, there is a dearth of knowledge on potential mechanisms underlying individual differences in emotionality to…

In order to examine (1) the stability of the mother-child-bond and (2) associations between mother-child-bonding and aspects of maternal-well-being, pregnant women (N = 170) completed measures on well-being and mother-child-bonding at two antepartum and two postpartum time points. We found relatively weak associations between mother-child-bonding…

The purpose of the study was to evaluate fine- and gross-motor development and basic cognitive skills in 3-18 month-olds in relation to home factors, age and weight. Three hundred and seventy mother-child dyads were recruited. For age, two groups were analyzed: 3-11 months and 12-18 months. Motor and basic cognitive skills were assessed using the…

Recent research suggests that infants prefer prosocial behaviour. However, some studies have failed to report this preference, raising the question of which specific parameters allow it to be observed. We attempted to answer this question by investigating whether the preference varies (1) with age (by testing infants aged 6, 12 and 18 months), (2)…

Although observational instruments are considered to be the gold standard for measuring toddler childcare quality, large-scale studies often have to rely on interviews or questionnaires. However, it remains unclear whether such reports can serve as reliable indicators for childcare quality. The present study used the ITERS and FCCERS to examine…

Parent adverse childhood experiences (ACEs) and caregiver reports of harsh parenting were examined in relation to the executive function (EF) abilities in young low-income children. Data were collected from 55 "mother-child" dyads; 17-40 months of age. Parent measures included the ACEs questionnaire and harsh parenting items from the…

We compared systematically the structure, the focus, the thematic sequences, the complexity and the syntactic properties between maternal and paternal infant-directed speech in engagements of infants with their mothers and fathers. Eleven mother-infant and 11 father-infant dyads were video-recorded during their natural interactions at home from…
