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…

The purpose of the current study was to use the infant sibling design to explore whether proband traits of autism and ADHD could provide information about their infant sibling's temperament. This could help us to gain information about the extent to which infant temperament traits are differentially associated with autism and ADHD traits. We used…

This study tested the hypothesis that exposure of children prior to their third birthday to procedures requiring general anesthesia is associated with an increased incidence of autism spectrum disorder (ASD) in later life. This study employed a nested, 1:2 matched-case control study design using ASD cases identified in a population-based birth…

There is a need for more research focusing on the health outcomes of infants born to the understudied group of adolescent mothers. Archivical data from four independent sources were used to answer the following research question: During the child's first year, what adverse health factors are associated with acts of intimate partner violence (IPV)…

We compared language comprehension and production across the second year of life in children of clinically depressed mothers who later remitted with children of nondepressed mothers. Altogether, 157 mother-child dyads participated: 46 with mothers diagnosed at infant age 5 months as having major, minor, or other depressive disorders who fully…

Previous research assessing consequences of interpregnancy intervals (IPIs) on child development is mixed. Utilizing a population-based US sample (n = 5339), we first estimate the associations between background characteristics (e.g. sociodemographic and maternal characteristics) and short ([less than or equal to]1 year) and long (>3 years)…

Infant and young child feeding (IYCF) is crucial for the growth, development, and survival of a child. This study aims to examine the factors associated with IYCF practices among the under-2 aged children in Bangladesh and spatial variability. A total of 2336 children aged 6-23 months were selected from the 2014 Bangladesh Demographic and Health…

We compared the structure and the content of mothers' and fathers' infant-directed speech as a function of infant birth order. Seven first-born and four second-born infants were video-recorded during their natural dyadic interactions with their mothers and fathers at home from the second to the sixth month after birth at 15-day intervals.…

Objective: To assess the relationship of moderate and late preterm birth (32[superscript 0/7]-36 [superscript 6/7] weeks) to long-term educational outcomes. Study Design: We hypothesized that moderate and late preterm birth would be associated with adverse out- comes in elementary school. To test this, we linked vital statistics patient discharge…

This study examines the relationship between the psychological states of Korean mothers and early childhood development. In the study, 480 mothers were classified into three groups: cluster A mothers were happy and competent, cluster C were depressed and stressed, and cluster B were neither depressed nor happy. The tendency of infant developmental…

Purpose: Marital dissatisfaction and conflict often increase for couples after the birth of a child and are evident in fewer positive family interactions and more negative family interactions. Because exercise is known to increase positive emotions and decrease negative emotions, the current study examined the extent to which higher levels of…

The developmental science literature is riven with respect to (a) parental similar versus different treatment of siblings and (b) sibling similarities and differences. Most methodologies in the field are flawed or confounded. To address these issues, this study employed a within-family longitudinal design to examine developmental processes of…

Adolescent motherhood is a risky situation related to poorer quality of infant caregiving. The lack of social support and increased odds for maternal depression are the main concerns. This study aimed to investigate whether maternal-foetal attachment, social support and maternal depression measured during pregnancy and after birth were associated…

This study investigated whether the amount and timing of group-based childcare between birth and 51 months were predictive of cognitive development at 51 months, taking into account other non-parental childcare, demographic characteristics, cognitive development at 18 months, sensitive parenting and a stimulating home environment. Children's…

While associations between exposure to marital conflict and child development have been documented extensively in middle childhood and adolescence, few studies have examined the developmental consequences of conflict exposure in infancy. Moreover, those that have examined marital conflict in infancy tended to focus on consequences of conflict…
