Just as with all areas of development, there are certain behaviors that are typical as children progress through developmental stages. These behaviors often challenge adults, but they are to be expected. The table below provides examples of the types of behaviors staff members may encounter with each age group. Share this information with staff members to help them prepare for work with children.
