Nap and Dora

I put Payton and Lincoln down for a nap and started my free time activities.  :o)  When all of a sudden I started hearing music, sounded like hispanic music.  I couldn't tell where it was coming from.  I was standing in the kitchen and our atrium door was open so I thought that maybe it was our neighbor, who is a DJ, playing music.  But the more I listened the more it sounded like Dora the Explorer.  I though, "There is no way the neighbor is playing Dora." 

That is when I realized the music was coming through the monitor and Payton was in fact watching Dora the Explorer on her Nook...How the heck does she even now how to do that?
