With 354,000 copies in print, <em>Really Important Stuff My Kids Have Taught Me</em> is the really successful book of sandbox wisdom. Now it is reissued with three fresh, appealing covers. <br> <br>Collected and edited by Cynthia L. Copeland, author of <em>The Diaper Diaries</em> and <em>Fun on the Run</em>, together with 170,000 copies in print, <em>Really Important Stuff</em> is filled with clear-eyed common sense that can make us start with surprise and delight. Here are children saying things that are smart, funny, innocent, completely sensible in a way adults just aren't. Things like: “Bees shouldn't be so nice and fuzzy.” “You can either keep pedaling, get off the bike, or fall over.” “Pants with pockets are better.” Things like: “It's more fun to color outside the lines.” “Lick your ice-cream cone before it gets a chance to melt.” “You're only little until someone littler comes along.” And, “Milk tastes better through a straw.”
