As any parent or teacher will tell you, children feel things deeply - particularly fear and love. One classic picture book explores these emotions in a sensitive and gentle way. In "Owl Babies" by Marting Waddell, three young owl siblings must wait for their mother as she hunts in the woods.
While the youngest cries, again and again, "I want my Mommy!", the older owls explain why she is gone. (Who among us hasn't wanted our Mommys, even as grownups?)
