"gog...gog...gog..."

Not real sure what he is trying to say exactly, but I think we might be on the brink of Hayden's 1st word... or pseudo-word.

Hayden loves to drive trucks, or cars, vehicles of any type really.  Sits & rolls them back & forth for long periods of time.  And while he drives them he repeats what sounds like "gog" (or maybe its "go") over & over.  (I like to say its "GOG," sounds better to me)  "Gog..go..gooo...gog..gooog...go...gog..."  Then yesterday afternoon as I was putting laundry away in their room, he spotted a Little People car.  As he crawled over to pick it up, he started saying "gog-gog-gog."  I think he knew what he was saying?... he spotted a "Gog."  Whatever a "gog" is??

When I play trucks with them... I say "vroom"
But Jeff said when he playes trucks, he says something that starts with a 'G' sound.  Something like "Grung... grung..."  (How do you spell jibberish-sounds?)  So maybe thats where he is getting it?  Or maybe its pure coincidece? 

He did the same thing for Jeff today.  Drove "gogs" all afternoon.  "Gog...gog...go...gog..."  And just as he was crawling across the floor repeating those 3 letters G.O.G., Jeff though, ok, nope its just a noise, he doesn't know what he's saying.  UNTIL... he realized he had crawled right to a truck!!

So what exactly is a "Gog".... I guess only time will tell!?
