Would be interested in seeing that link for sure

Is there a way you can make a "center" in a corner using a super-gate or low shelves that only the 3+ year olds are allowed in? I don't know your set up, but that might be an option, if you have the space.
Edited to add: I"Oh Dang! I just looked at that link...the ideas! Wow! Can't stop...looking....!"
