Watch Me Do It

Parent demonstrates a simple object-use action and watches whether child imitates it correctly — using the object as it was designed to be used. Covers observational imitation and object-proper-use milestones at 12-18mo. Three phases: familiar object demo, novel object demo, and spontaneous imitation observation.
