We got a puppet for Ethan last year:
He never really got that into it but recently he dug it out of his toy box. I started playing around with it and animated it for him with my hand. He looked at me curiously, then placed the puppet on his own hand and said in a falsetto voice 'I'm a chin wah (frog). I'm a good boy." The puppet then gave me a kiss. *so cute!* He will now puppeteer for my benefit a few minutes a day. We will see how long this lasts.
