Two Word Phrases

In the last week, John David has finally started to put two words together on his own.

"Buh-Bye Mama!" (Said as he leaves the room & blows me a kiss).

"Buh-Bye Tuttle!" (This is what he says when we come out of a tunnel---there are several in Pittsburgh).

"Yeah Mama." (When asked if he wanted some water).

He also has sound effects for the following animals:

Giraffe (smacks lips)

Lion (Roar!)

Dog (pants)

Monkey (eeee---eee--eeee)

Duck (quack)

Alligator (chomps his teeth)

Snake (SSSsssssssss)

Owl (whooo whoooo)

Octopus (waves his arms around)

There are probably more but this is all I can think of at the moment. He keeps asking me "Coon?" He wants to know what a raccoon says. I have no idea. Can someone tell us?
