There is a considerable delay between the time parents suspect their child may be developmentally delayed and the time a formal diagnosis is made, often followed by an even greater lag before treatment services are started. However, treatment and intervention programs are most effective when started as early as possible. This study will attempt to validate a non-invasive early intervention protocol for children starting at 3 months of age. Infants will participate in an in-home, parent-guided training program using “Sticky Mittens” (infant mittens with Velcro attached to the palms) and Velcro toys, which will provide infants with reaching and grasping experiences. Typically, infants engage in successful reaching and grasping around 6 months of age. Through the “Sticky Mittens” used in this study, already 3-month-old infants will be able to experience successful “grasping” before they are physically able to do so and provide them with novel experiences important for learning. The goal of this study is twofold: First, to provide infants with experiences of self-initiated, exploratory activities (a common treatment goal for older toddlers with autism). And second, to determine whether failure to benefit from the training procedure indicates a potential red flag for autism regarding the child’s ability to learn from self initiated play experiences.
