What Ducks and Trucks Share

Nothing much actually, except for the fact that my son pronounces them the same way. However, instead of the "D" or "Tr" sound, Liam has found a way to consolidate several consonants into the letter "F". So if you see my son and I walking along side a busy road, or strolling past the pond in the park, and you hear my son yelling "F#*%, F#*%!!!", he is NOT saying what you think he is. I did NOT teach him that. And please do NOT start laughin-that will only prolong his fascination with the word.
