Is there anything so heady or contagious as the shiny, new confidence of a child who has freshly mastered the everyday, but oh-so-difficult? No matter that a few drops of juice miss the glass, or that her buttons are a bit askew, the lively little heroine of this satisfying story absolutely exudes positivity and innocent pride in newly-acquired skills. With bright, broad, touch-me artwork and easy-on-the-ears rhyming text, Wilson-Max and Baicker conspire to communicate, most successfully, the infectious exuberance of their cake-baking (okay, batter-testing), trike-riding young subject. (P.S. Thanks for the helmet.) This sturdy cardstock offering has plenty of finger-paint child appeal: each carefully composed page depicts the earnest little girl’s effort to replicate the activity of a nearby friend or family member, and artfully integrated, actively designed type swings and sings and whooshes across paintings that pronounce her hard-won self-assurance with a boldly saturated palette. Physical skills are not the only kind in focus here, for a happy contagion of kindness is also afoot. The support of her family and congenial companions has the very finest of effects, and best of all, at the end of it all, is our little heroine’s unspoiled and generous display of encouragement for one even smaller than she.
