Early childhood development is a multi-sectoral issue and refers to children aged 0-8 years, or from birth until the commencement of primary school. It is an important time in a child’s life, so access to adequate nutrition, early stimulation, positive interaction with caregivers, play and learning opportunities and protection from violence and neglect is vitally important in order for children to develop their potential. This is a crucial time to ensure that children with disabilities access the necessary services, due to the rapid rate of growth, learning and development that occurs during a child's early years. The development achieved in this period provides a foundation for later learning, skill acquisition, social and emotional development and behaviour.
