When it comes to picking children’s books, I am a lot like those old ladies you see in Upper West Side supermarkets, tapping, squeezing and smelling the melons on display: “Is it ripe, dear?” Bringing a children’s book into your home is not something to take lightly. An obliging parent may be asked to read it a hundred times. Nay, a thousand times. The big-eyed sheep that seemed so cute while you were flipping through pages in the store soon begins to vex. Over time, reading the book becomes like ripping off a Band-Aid. Even small defects — an irritating drawing, the misuse of the word “presently,” a character who speaks in rhyme — can form blisters on the parental soul. No, darling, not again. Let’s pick another book, please. I’ve seen the best minds of my generation destroyed by the 38th reading of “Knuffle Bunny Too.”
