The first years of development are crucial for lifelong learning and development. Developmental milestones are actions that most children can do by a certain age. Milestones follow predictable courses in infants and children, and later, developmental skills build on previous ones achieved. Understanding normal development can help recognize delayed development. Children with global developmental delays have delays in multiple domains of development, while children with specific delays may have a delay in only one area of development, such as language or motor skills (Scharf et al., 2006).
