The mice will play! Sometimes I have to leave the room for a minute. I'm learning to wait as long as possible to leave the room, and to make sure nothing "bad" can happen while I am otherwise occupied. We also have locks on the pantry door and a gate on the playroom. One morning, I let the kids play with stickers on some paper while Elin was having Tummy-Time. I thought everyone was pretty well occupied. So, I snuck out for a minute (I drink a lot of water). I was gone for no more than three minutes! It's a good thing she is such an easy-going baby who likes attention from them. She may not survive long otherwise. We are also getting more/higher locks on all the doors to the outside world. They've been able to reach the locks for a long time. They just recently decided that they're going to use their skill. Olivia, especially enjoys going outside while Mommy is putting Elin down for her nap. Aislee likes to open the door, but her irrational fear of buggies keeps her on the door step, while Olivia takes off down the drive way and Ewan hurries after. No one has been hurt. I have suffered a few near heart attacks. We've had a few talks about cars, scary strangers, and the fact that bugs will eat your toes if you go outside without Mommy or Daddy. Olivia hasn't done it for quite a few days! And, I'm getting better at shutting the gate to the playroom when I put Elin down for her nap. Better to have angry toddlers than something much worse!
