Ever since Emmy started moving, we created a jailing system – we simply have an ottoman (that she can’t quite climb yet) blocking the way out of the family room. If I’m in the kitchen, I can still see everything, so it works.
Today I had a thought: I should give Emmy freedom. And then I casually moved the ottoman.
She instantly darted for the stairs. While I was setting up a stair blocking system, she ran into the kitchen and knocked over a water. While I was cleaning up the water, she found an (poisonous) ant trap in the back of the pantry and tried to eat it. While I was throwing the ant trap away, she fell while trying to get onto the window ledge and bonked her head.
It has been seven minutes since I had my thought and Emmy now is back in her living room jail.
