Featuring three children of different ethnicities, 26 soporific vignettes, from ``A—all ready for bed'' to ``Zzzz.'' ``D—dreams forming,'' ``E—eyelids growing heavy,'' ``J—just one more story,'' ``T—tucked in tight,'' ``V—voices from the other room.'' The well-ordered sequence of cozy, familiar things leads ineluctably to sleep. Hays's quietly glowing colors, plump, solidly formed little bodies and contented faces all add to the sense of security. A lovely way to unwind at the end of a busy day. (Picture book. 3-7)
