Car rides nowadays are filled with loud exclaimations from K. He hollers excitedly when he sees trucks of any sort and bellows when a double-decker bus passes by. I will exuberantly point out how big, high or long the trucks are and enthusiastically describe the things that I see in the truck's cargo. This is probably one of the best way that I know of that can keep my toddler happily occupied during long car rides.
So naturally, one of the new words that we have heard recently is "Dump truck". I find it quite amusing how the word sounds when he says it.
