Plan Toy Stacking Ring Pyramid - task accomplished

Well, Adrian is finally able to assemble the Plan Toy Stacking Ring Pyramid in order, not by accident, & without any verbal guidance. It has been a long journey - he had stacked it in order in the past, but when I would ask him to repeat the activity, he would make a mistake. This time, he was confident & could stack it in order every time.

This pyramid is one of the favorite toys of both Julia & Adrian, &  to me it is classic & timeless. Well, may be I will keep it on the shelf for a little longer to reiterate color recognition.
