these are the words jack knows, jack knows, these are the words jack knows

Wow! At the risk of sounding like a doting papa (a risk I'm wiling to take!), we recently compiled a list of words our little man knows and uses fairly regularly: Teeth. Up. Down. Avocado ("ah-doh"). Bus. Truck. Milk. Juice. Toast. Nana. Papa. Mama. No. Daniel ("Dano"). Baby. Arm. Eyes. Nose. Hair. Turtle. Tomato ("may-mo"). Banana ("nana"). Spoon. Hot. Tractor ("tah-tah"). Video. Keys. Ball. Pasta. Spaghetti ("beppi"). Puppy. Bird. Boat. Phone. Apple. Gentle. Uh-0h. Bye-bye. When did this happen, exactly???
