He wants to do everything like a "boy boy" (big boy), he loves to point out "trappers" (tractors), and he loves everything. "I love those horsies, Mama!" "I love both of those colors, Mama!"
His understanding of the world around him is delightful. At swimming lessons as I was doling out pairs of goggles, it was, "I want my goggles on my three-head Mama."

Isaac frequently gestures toward my stomach and says casually, "There's a baby in there." Tonight at dinner was one of those times. Then I was eating a gingersnap, and he wondered, "When you eat that cookie, then it goes down into your tummy and then the baby eats the cookie?"
Shortly after that, "Mama, you could rip off your head and then the baby could come out of your neck."
