He has a bunch of new words now, like "air-pane" (airplane), which Grandpa ("yeh-yeh") taught him because he kept pointing to aircraft and calling them "bird".
His other words are pik-chur, ba-nana, papa, car (followed by a "vooom"), dog (followed by a "wo-wo") chie chie (sister), mum-mum (for food and for mommy), ishh (fish) and the sound of a sheep ("aa-aa-aa").
To the right is my fish tank with its new inhabitants. The former inhabitants died due to an unfortunate incident. So now I have schools of guppies (the more expensive hardier sort, not the $2 for a bag sort), Cardinal Tetras, Rummy-nose Tetras, Emperor Tetras, and a fish I cannot the remember the name of (looks like a swordtail but is short and fat).
