Crawling is considered an important motor skill for infants. Although infants show variations in their crawling, the association between crawling variations and subsequent development is unexplored. This study investigates the difference in amount of crawling variation between infants with and without subsequent developmental delays. This…

This was a cross-sectional study that aimed to evaluate the association between breastfeeding and motor development of infants at 3-4 months of age in the city of Pelotas, Rio Grande do Sul. The outcome, infant motor development, was evaluated through the Bayley Scale of Infant Development (Bayley III). The prevalence of infants that stopped…

Background: Several studies have reported low adherence to World Health Organization sedentary behavior (SB) guidelines in the early years. The purpose of this review is to examine the associations between time spent in different types of SB (screen time and habitual SB) and motor competence (MC; fundamental motor skills, fine and gross motor…

Infant motor development is affected by the sociocultural context in which it takes place. Because societal and cultural practices are dynamic, this exploratory study examined whether the ages at which infants typically learned to crawl, cruise, and walk changed over the past 3 decades. We compiled archival data from 1,306 infants born between…

How do age and the acquisition of independent walking relate to changes in infants' everyday experiences? We used a novel ecological momentary assessment (EMA) method to gather caregiver reports of infants' restraint, body position, and object holding via text messages sparsely sampled across multiple days of home life at 10, 11, 12, and 13 months…

The first years of life are an optimal time for developing motor competence. However, the evidence regarding motor competence in early childhood is fragmented and needs to be clearly synthesized and presented. To establish effective evidence-based decision making in research, practice, and policy for the early years, this expert statement, on…

Due to the lack of tools that can be easily used by practitioners, there is a need to develop acceptable embedded ways to assess children's fine motor skill development within early childhood education and care settings. This study examined the validity and reliability of a brief and ecologically valid fine motor assessment tool for preschool-aged…

Enhancing executive function in children and adolescents can have significant positive impact on their current and future daily lives. Upregulation of executive function associated with motor skill acquisition suggests that motor learning scenarios provide valuable developmental opportunities to optimize executive function. The present systematic…

Fragile X syndrome (FXS), the leading heritable cause of intellectual disability, has a co-occurrence rate of autism spectrum disorder (ASD) estimated at ~60%. The onset and rates of motor development in FXS are slower relative to neurotypical development, and even more so in the context of co-occurring FXS + ASD. Extant evidence suggests these…

We aimed to calculate interrater reliability of the Test of Gross Motor Development--Third Edition (TGMD-3) after raters reached a consensus regarding measurement criteria. Three raters measured the fundamental movement skills of 25 children on the TGMD-3 at two different times: (a) once when simply following the measurement criteria in the TGMD-3…

Extracorporeal life support, such as pediatric cardiac extracorporeal membrane oxygenation (ECMO), is associated with significant mortality and morbidity risk. This study evaluated cardiac ECMO survivors with central cannulation and found that 51.1% were discharged from the hospital. The study also revealed high rates of developmental delay…

Forest school is a form of outdoor learning that takes children into regular and repeated learning experiences in natural settings. Being based on a comprehensive experience with nature, it is assumed to be beneficial for learning and to promote restorative effects on cognitive and emotional function in preschool children. This review aimed to…

This study reports on crawling variability and differences in variability between infants with typical development (TD) and those with developmental delays. This longitudinal study included 0-year-old infants with no apparent dysfunction. The crawling movement in the video was coded objectively with reference to previous research. The infants were…

Early exploratory behaviors have been proposed to facilitate children's learning, impacting motor, cognitive, language, and social development. This study related the performance of behaviors used to explore oneself to behaviors used to explore objects, and then related both types of exploratory behaviors to motor, language, and cognitive measures…

Purpose: This case series documents developmental changes over time and in response to a novel intervention, Sitting Together and Reaching to Play (START-Play), in children with early-life seizures. Methods: Thirteen children with early-life seizures were included from a subset of participants in the START-Play multisite, randomized controlled…
