Background: Maternal input plays an important role in influencing linguistic development during the first years of life, and it is evident that mothers adapt their language according to their child's characteristics. Recently, it was demonstrated that maternal input addressed to children with sex chromosome trisomies (SCTs) at 8 months of age is…

What is vision's role in driving early word production? To answer this, we assessed parent-report vocabulary questionnaires administered to congenitally blind children (N = 40, Mean age = 24 months [R: 7-57 months]) and compared the size and contents of their productive vocabulary to those of a large normative sample of sighted children (N =…

Research suggests that elements of the family environment may have significant associations with cognitive and language development outcomes. Less is known, however, about the family environment in peri-urban China, where rates of cognitive and language delay in children aged 0-3 years are as high as 51% and 54%, respectively. Using data collected…

Sometime before their second birthday, many children have a period of rapid expressive vocabulary growth called the vocabulary spurt. Theories of the underlying mechanisms differ: Accumulator models emphasize the accumulation of experience with words over time to yield a spurtlike pattern, while cognitive models attribute the spurt to cognitive…

Language ability has been associated with emotion regulation (ER) ability. Children on the autism spectrum have greater rates of language delays and lower ER ability. Despite this, autism traits have not been considered or controlled for in past research. This study therefore examined the association between language ability and ER in young…

This 3-wave longitudinal study investigated the developmental trajectories of instrumental helping, sharing and empathic helping across toddlerhood, and how socialisation processes (i.e., parents' and teachers' practices) contribute to these developments. Participants were 50 18-months-olds and 62 24-months-olds, their parents, and daycare…

We examined maternal prenatal vitamin use or supplemental folic acid intake during month one of pregnancy for association with autism spectrum disorder (ASD) in the Early Autism Risk Longitudinal Investigation, an enriched-risk pregnancy cohort. Total folic acid intake was calculated from monthly prenatal vitamins, multivitamins, and other…

The U.S. Preventive Services Task Force (USPSTF) report on screening for Autism Spectrum Disorder (ASD) highlighted the need for research that examines the harms potentially associated with screening so as to assess the overall net benefit of universal screening. In response, this study engages qualitative, semi-structured interviews to generate a…

This qualitative descriptive study was designed to answer the following questions: How do infant/toddler teachers (ITTs) enter the infant/toddler workforce? What motivates teachers to work in the infant/toddler workforce? What recruitment strategies are identified by experienced ITTs? What retention strategies are identified by experienced ITTs?…

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…

Toddlers contribute to early childhood education and care (ECEC) environments in unique ways in contrast to older children and adults. In this article, we explore early childhood teachers' stories about toddlers, thinking, and time. We follow a moment with a toddler's story told with his fingers, and discuss it through teachers' stories. Our focus…

Childhood states are commonly invoked by adult humans in derisory ways and as put-downs. While infantile and clownish ways of behaving are often met with insult, we argue that these ways of being could instead be seen in terms of their productive potential. Drawing on posthuman and feminist theories and invoking clownish qualities of Haraway's Bag…

This paper reports on a design oriented study conducted in close collaboration between two researchers and three preschool teachers. Within this study, a play-based interview script was designed in accordance with theoretically driven principles. Based on this script, the preschool teachers conducted interviews with children from three preschools…

Evidence supports early intervention for toddlers with ASD, but barriers to access remain, including system costs, workforce constraints, and a range of family socio-demographic factors. An urgent need exists for innovative models that maximize resource efficiency and promote widespread timely access. We examined uptake and outcomes from 82…

Though fatherhood research has recently burgeoned, extant literature primarily focuses on father characteristics and father--child interactions. A critical gap remains in understanding fathers' emotional experiences. Using the Parent Development Interview-Revised, 74 interviews with fathers of toddlers were coded using questions about six positive…
