That's it really. I need to be able to divide our our living room into two, so that 10 month-old DS stops messing up 3 year-old DD's toys. They need their own space 
So I've seen that the Babydan playpen can be used as a room divider, using wall -mounting kits. But I'm worried it will be wobbly, and not withstand DS and DD grabbing/shaking it, generally being kids
Thanks :)
