Although they still love their trains, the boys have a new obsession- superheroes. Specifically, superheroes from the DC Universe. Batman and Superman can be seen running around the house at pretty much any time of the day. The capes go almost anywhere we go, and the boys even sleep in them. At first, I didn't want to let them wear the capes outside the house, to bed, etc. But then I thought, you're only three once. For how long in your life do you get to truly believe you are a superhero? So, I just go with it. They can't wear them everywhere-- I draw the line when it's not safe (ie, at a playground) or when it's not appropriate (ie, Jen's wedding), but otherwise, their alter-egos have free reign.
Even members of the Justice League need to have their capes cleaned.
