Just as you mastered the art of packing the perfect diaper bag, he’s potty trained and headed to preschool. Help him make sure he’s got this one in the bag.Step One: Find the perfect carryall. It should be big enough to hold essentials (a snack, a sippy), but not so large that it weighs him down. Our pick: the handmade cotton and linen messenger bags from Mee a Bee ($25-$40), sized to sling across the chests of scholars ages 3 to 6.Step Two: Leave a paper trail. Ecojot’s latest collection of spiral-bound sketch pads and journals ($4.50-$17) supports the Jane Goodall Institute with collage-inspired cover images of endangered species. But it’s the recycled, unlined paper and heavy-duty back cover that give kids what they need to write and draw.Step Three: Color it in. P’kolino’s art set ($20) is a cornucopia of jumbo markers, triangle and wrapper-free crayons, and hexagonal colored pencils — all designed to fit little hands. So practicing good form is as easy as one, two, three.Looking for the perfect lunch box? Check out our photo gallery.CROONKids KaraokeWhat: Wannabe rockers belt out some tunes.
