From Emmy Award nominee and author-illustrator Steve Small comes a picture book about the bond between father and son, being little, and growing up one day at a time.

When Wellington is given a new jacket exactly like Dad's for his birthday, he's delighted! But his delight turns to disappointment when he tries it on and it's far too big. Even worse, what if it's not that the jacket is too big, but that he's too small? Luckily, Wellington's dad has a plan, and on an exciting day out that includes a ride on the bus, a super-size strawberry sundae, a toot on a tuba, and a visit to his granddad, Wellington learns that he's growing up exactly as fast as he should be—and just like his dad.
