This book was a gift and I originally thought that it was too detailed to be interesting to my 22-month-old son. However, it has a very calming quality and he insists on it every night before bedtime. The adventures move along frequently enough to hold his interest, without being overly stimulating. And he can identify elements he likes from the drawings, such as the propeller, the wind sock, the hangar, and the car on the ground.His father and I appreciate the accurate details. I'm now on-line looking for other books by Lois Lenski, hoping that they, too, will be a hit for us.
