I offer this story to explain how I have come to be fascinated with working with children ... Today I worked the toddler nap time , filling in while the regular teachers had breaks , alone in a room with 9 sleeping children and one cranky wakeful child . She wanted her mommy , she screamed and cried for mommy . I spent the entire hour dreading that she would wake one of the other children , fighting to keep her on her mat and not screaming , mutually exclusive goals . Oh , and ideally , she would get a good nap , too , before naptime was finished .
