Somedays it seems as if Cate (3) and Noah (2) carry on an argument from the time they wake up until the time they go to bed, punctuated by pushing, screaming, crying, and the like. They're tiny, inseparable curmudgeons. "Nuh-uh," is their favorite response to the other. Noah likes to tack on a belittling, "Baby!" (Which we are working on.) An old, little married couple, each too afraid and too in love to be without the other.
