Toddlers love to open and shut things repeatedly. Doors, cabinets, etc. But especially doors. If you find yourself simply taking the dog outside, be sure to turn that tiny lock on the door knob so that it doesn’t automatically lock once shut by said toddler. Think about making a fashion statement by wearing a house key around your neck. I’m kidding. Kinda. Or, make sure you have lightening fast reflexes that allow you to run at warp speed towards the door as you see it swinging shut in slow motion yelling “nooooooo!” like a bad action flick. Your toddler thinks this is hilarious. I learned I have those reflexes today. Thank goodness. Also make sure your sister who lives 4 blocks away has your house key and carry your cell phone at all times.
