Cassandra's Darth Vader imitation is quite impressive.  In addition to the look, the triangle has a small hole in it so her breathing even resembled what you hear when watching Vader on screen.

Grandma Wendel and Daddy's cousin Theresa make a cloth "book" for Cassandra.  Various pages show how to button buttons, work a zipper, and tie a shoe, as well as peek-a-boo and may others.  She enjoys reading the book on her own but will bring it over to us and want to sit in our laps too.

Cassandra is very proud of her ability to sit in a chair without help.  She generally claps upon completion of this task.
