I remember watching an episode of one of the Dilley Sixpack shows with Diane Sawyer several years ago when the kids were small. They were trying to keep them in their playroom, and the kids were climbing over the vertical bar gate using their toes. So they tried putting vaseline on the bars so they would slip, but the kids got over anyway. They tried putting a second vertical gate above the first one, and greasing those bars, and the kids still got out. They ended up putting a third gate on top...that kept them in. LOL...why not just install a door...
