From the day your baby is born their brain is growing and developing. They learn by connecting with people so it’s important for parents and carers to provide them with as many learning opportunities as possible to encourage their development.

The following information has been sourced from the Early Years Learning Framework Developmental Milestones booklet, developed by Community Child Care Co-operative Ltd NSW (CCCC) for the Department of Education.
