Sound speech

Sheep are "baa", cats are "meow" and butterflies are mearly a fluttering of the hands over his head. Ian refuses to say an animals' name. If he sees a cow, he says "moooo". If there is a dog barking in the neighborhood, Ian barks too. When he sees an elephant in a book, he raises his arm to his head and rears back, trumpeting.
"Look, Ian! A monkey! Say 'MONKEY', Ian!" Ian will just look back with his enormous brown eyes, bring his hands up to his chest and grunt, "Ohh Ohh Ohh" and sign for a banana.
"Ian can you say HORSE? Say HORSE, Ian!" And Ian will whinny, "Neigghh!"
"A dinosaur, Ian! Can you say DINOSAUR?" Ian drops his chin and lets out a terrifying growl.
Animals aren't the only things that just have sounds. Airplanes are signified with the ASL sign and a gutteral sound. Motorcycles get more of a throaty voice. The trash truck is more of a worried look, with furrowed eyebrows, and a louder, deep sound, as he is nervous of the real sound of the trash truck.
But mostly this "sound speech" is centered around the various animals he sees around him and in books. Fish are signed, and though "ish" was one of his first words, he seems now to have abandoned it. There are three animals that have names: mouse, duck, and bird. Why, I don't know!
I know that soon enough, Ian will start calling a pig, a pig, instead of sniffing like he does now. And a frog will no longer be the deep "ribb" and the chicken won't be a "brok-brok". But the sound I will miss most will be his tiger/lion/dinosaur sound. A wonderful, low, long and loud "ROAR!!!" that seems to come from some primal place inside him. He'll know that everything has a name, himself included. And that somethings have many names, like Ian can also be called a son, grandson, brother, toddler, then boy, soon to be teenager, man, father, and grandfather. All in the blink of an eye.
