The presentation outlines how developmental milestones are affected by disabilities. It discusses normal milestones for non-disabled children in the first half. The second half explains how specific disabilities can impact milestones and provides evidence-based teaching strategies to help overcome challenges. Some disabilities that are discussed include intellectual disabilities, specific learning disabilities, physical disabilities, emotional and behavioral disorders, attention deficit disorders, and autism spectrum disorder. The presentation emphasizes that while disabilities may affect development, each child grows at their own pace.
