We have a custom made Viv. It is all glass. The front access doors meet each other in the center. They do not over lap one another. We are concerned about little ones sliding the doors open and we won't notice. Does anyone have a idea for a quick and easy lock? Is there such a thing as a stick on lock? I am thinking Velcro would work for now but that would be figured out quick. When we bought this viv we didn't quite think about all the what ifs...the doors will pose the biggest issue.
