Grownupish grownup . . . What in the world does that mean?! Babysitting should be pretty straightforward: if you give the child a chocolate soda, he’ll do his homework. Unfortunately for Mr. Nogginbody, he follows those steps in that order. When the child refuses to study and begins jumping on the couch, Mr. N. jumps up after him, determined to put a stop to the shenanigans. But he quickly discovers just how much fun being a kid can be. There’s a fine line between childish and grownupish, as readers will learn in this playful and brilliantly accomplished new picture book from Caldecott Honor–winning creator David Shannon.
