Annalee Escape Artist

Annalee is stating her indepedence. She has left the house twice now without me knowing. I hear a door slam and I run outside to look for her. I put the chain on the door and she sled through the crack. I have to rig it shorter so won't get out. I don't know what I'm going to do when it is too hot to leave the door close. She is now going off without her sisters when playing outside. When it is time to come in she walks around the fourplex to the front and tries to hide from mom. How can someone not love that face?
