After busy days flying around the world, chasing villains, and keeping people safe, DC's beloved super heroes need to go to sleep. Super heroes in training will definitely relate to this charming bedtime book. Like the other bestselling DC Super Heroes board books (ABC 123, Colors and Shapes, Opposites, Busy Bodies, My First Book of Super Villains, and My First Book of Girl Power), Even Super Heroes Sleep uses DC's classic art to illustrate fan favorite characters getting ready to re-charge. Batman knows his brain works best after he's gotten a good night's sleep (Goodnight Gotham City!). Green Lantern needs his Power Battery, and Superman's super-strength fizzes out at the end of the day.
