This page just introduces the demonstration. The moving blue square represents a child's age from birth (B) to 6 years old. The square spans 1 month. When the blue square jumps back to B it represents a different child. The number of children viewed so far is shown in the bottom left of the display. Use the slider to speed up or slow down the rate at which children age. When you are comfortable with what you are viewing, click NEXT (top right) to go to the next page.

You can click NEXT or BACK at any time to move between the pages of the demonstration.

You can use the speed slider at any time.
