Maternal substance use and unpredictable maternal sensory signals may affect child development, but no studies have examined them together. We explored the unpredictability, frequency and duration of maternal sensory signals in 52 Caucasian mother-child dyads, 27 with and 25 without maternal substance use. We also examined the association between…

This study explored the experiences and perspectives of Latinx mothers of children younger than 3 years who had participated in a developmental screening initiative provided by 2 Federally Qualified Health Centers in an urban setting, had positive developmental screenings, and were referred to early intervention (EI) services. A 2-phase…

This study aimed to verify the course of maternal anxiety disorders and its impact on child development of toddlers. This is a cohort study that followed 497 pregnant adolescents who received antenatal care in the public health service in a southern city in Brazil. We assessed maternal anxiety disorders during gestation, postpartum, and when…

Childcare services are widely used by families and thereby exert an important influence on many young children. Yet, little research has examined whether childcare may impact the development of child executive functioning (EF), one of the pillars of cognitive development in early childhood. Furthermore, despite persisting hypotheses that childcare…

This study explored child behaviours that enable mothers to perceive their child's minds. We administered the Mind Perception Questionnaire to 216 women with children aged between 0 and 24 months and 221 working women without children. Participants responded with mind perceptions for various entities, including for their children (a 0--2-year-old…

Purpose: To investigate the language environments experienced by preterm-born infants, this study compared the linguistic and interactive features of parent--infant conversations involving 2-year-old preterm- and term-born infants. The study also explored how mother-infant and father-infant conversations may be differentially affected by…

Researchers and practitioners need robust measurement tools for evaluating knowledge of child development to better support parents and their children during pregnancy and the transition to parenthood. We addressed this need by evaluating the psychometric properties of the Domains of Development Instrument (DoDI) for measuring knowledge of…

We report two studies that investigated the continuity and stability of maternal mind-mindedness (MM) across different times, contexts, and relationships, and also examined child communicative development in the second year of life. Three main findings emerged. First, the percentages of appropriate mind-related comments (AMRC) decreased between 16…

Prenatal folate and vitamin B[subscript 12] status have been linked to child neuropsychological development, but less is known about maternal genetic influences on this association. We conducted an exploratory longitudinal study of 181 mother--child pairs to assess whether maternal MTHFR 677C>T genotype modifies the association between maternal…

Parenting is a key factor for the development of children with intellectual and developmental disabilities. Therefore, early intervention programs should target parenting behaviors to improve children's developmental outcomes. The present study analyzed the effect of parental behaviors and other family factors on the cognitive and linguistic…

This study, using longitudinal data from the South African Birth to Twenty Plus study, assessed associations between early childcare quality in the home between six months and two years, household SES and cognitive development at age 5. Childcare quality was assessed using measures of maternal responsiveness and cognitive stimulation. Cognitive…

Supportive early relationships are critical to young children's development. Previous research has focused primarily on aspects of specific parenting practices that impact infants' and toddlers' development. However, additional research is needed for a more nuanced understanding of the relationships among family experiences, parenting behaviors,…

Infants and toddlers experience the world in interaction with others. Likewise, social interactions are important in learning about math--concepts of number ("one," "two," "three"), space ("on top," "upside-down," "round"), and magnitude ("more," "big,"…

Community health workers possess valuable insight into the experiences of South Africa's children and caregivers. However, their knowledge is often overlooked in efforts to understand local realities, inform interventions, and develop relevant policies. This study aimed to explore community health workers' perspectives of the first 1000 days of…

Globally, an estimated 15 million children are born prematurely each year, resulting in a high burden of under-five mortality and neurodevelopmental disability. Kangaroo Mother Care (KMC) is a key intervention to support the development of preterm infants. However, evidence on the impact of KMC in routine care settings remains limited. This paper…
