We were reading downstairs in her bedroom before morning naptime (and after playing with every toy, zooming around in her sled, talking puppets and mooo and baaa and bow-wow-wow ... she really gets excited with all of her things in the playroom!!). I left her sitting in her bedroom with a book for just a few moments while I literally ran up the stairs to grab her pacifier and blankie. I pulled the door at the bottom of the stairs closed, but didn't latch it. And when I started back down the stairs, there was Eva (all smiles!) upstairs in the entryway. I nearly had a heart attack!
