Our bedroom and bathroom doors have the old fashioned European keys. Now I know most people just leave them in the lock, but not us. Our first night here, Justin locked himself in the bathroom and couldn't figure out how to UNlock the door. We removed the keys. While I doubt he would repeat the incident, Ryan might. Even if no one got locked in, keys would likely get removed and put in a special safe place never to be seen again.Now believe it or not, there are times when we MIGHT want to keep the kids out of the bedroom or bathroom. Since Ryan has now learned to open doors (stupid easy to open handles instead of knobs), it seemed wise to have keys reasonably accessible. A hook on the back of our bedroom door is an ideal place. Less than an hour after I had added the keys to the hook, Ryan came to me and took me to the door. He pointed up to the keys and made unhappy grunting noises. He doesn't miss a thing. It makes it very hard to put anything past him.
