The purpose of this series is to help parents and caregivers recognize normal child development milestones and to provide age-appropriate activities, nurturing and guidance. Each child is unique. Rates of development can differ widely among normally developing children, and each child can have “fast” or “slow” rates of development in different areas and at different stages. These descriptions are merely based on typical behaviors and developmental milestones for the age. If your child is not exhibiting “normal” developmental behaviors, there is no cause for alarm. However, discussion with a development specialist can help you determine if any special interventions are necessary.
