Time for Bed Board Book by Mem Fox (Author) & Jane Dyer (Illustrator). Ages 1 and up. Darkness is falling everywhere and little ones are getting sleepy, feeling cozy, and being tucked in. It’s time for a wide yawn, a big hug, and a snuggle under the covers -- sleep tight! Working beautifully with the soothingly repetitive text, each painting conveys a warm feeling of safety and affection.
