Like last night when he pretended his books were "nacks" (snacks) and kept pretending to gobble them up. Then he proceeded to give our cats, the couch, the TV and me all a "bite." When it came to feeding the inanimate objects, he even made the gobble noises for them.
Or when he sings the Happy Birthday song for no reason other than it's one of two songs he actually knows. But when he sings it, he belts out on repeat, "Happy, To YOU!" because he can't say "birthday" yet. (the other song he knows is the theme song for the show Two and a Half Men- he sings, "manly man man, oooooohh").
Or when for the first time last night, he grabbed his cheek and said, "piiiiiinch" after I've done the exact same thing to him a million times. That same night he also, completely out of the blue, said "knock, knock" while "knocking" on my head.
And when we saw tractors on the side of the road and I said, "Look Jacob. Tractor!" And he corrected me, "No mama. Two tractor." OR when he correctly identifies and names the following: articulated truck, dump truck, garbage truck, excavator, grader, planer, skid steer, double drum compacter bulldozer, tractor, van, and jeep. I mean, the kid's only 20 months for heavens sake! That just goes to show the power of a little boy's obsession I guess.
