Sunny Day

Four tiny square books by Carmel O'Mara will show the littlest ones what can happen in the morning, in the night, on a rainy day and on a sunny day. The tender watercolors in Good Morning and Good Night show a bear cub stretching, giggling and hugging at daybreak, and yawning, bathing and finally going to sleep at day's end. In Rainy Day, rabbits splash, cuddle and read, while bears climb, roll and imagine in Sunny Day. ( Mar.)
