Siodore
Preston & Clare are my neighbors. I had the opportunity to babysit them today. Preston smartly chose the blue cup and Clare chose the green cup. Preston smartly informed me today that his cup's name was Simon, and Clare's cup was named Theodore. If only Isaac had a red cup, he could have been Alvin, but instead, he's a mix of Simon and Theodore. We could possibly dub him Siodore, maybe.
