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 Ages and Stages Questionnaire (ASQ-3). Home were evaluated using the Affordance in the Home Environment for Motor Development-Infant Scale (AHEMD-IS). In the 3-11 month old group regarding home factors, 'daily activity' predicted fine- and gross-motor skill. Results for the 12-18 month old group were different; gross-motor toys (GMT) and fine-motor toys (FMT) were significant predictors of motor and basic cognitive skills. Our findings suggest that during the first year, parental stimulation was a primary component, whereas toy availability during the second year played an important role in overall developmental status.
