Mom, It's My First Day of Kindergarten! by Hyewon Yum
It's a child's first day of kindergarten, but who is worried about all the new people and the different things he'll meet--the child? No! The mother. In a refreshing reversal of roles, the child takes it upon himself to comfort and reassure his mother that everything will be fine, she'll get used to him going to big-kid school, and yes, he is ready for the first day of kindergarten. Utterly charming in its simplicity, Yum playfully uses size and color to reveal emotions of this milestone beginning.
