Yahoo! I found a solution. My playroom is down 6 or so stairs from the next level (where the closest bathroom is); so I've placed the potty at the top of these stairs (back a bit for safety, of course)...this way the babies can't get at it and he doesn't have to come get me to access the gated area. This has been working fantastic, the last 2 days no accidents at all, he just runs up the stairs when he has to go (just like my other trained ones who run up the stairs to that closest bathroom).
