I've finally taken the gate down!! Baby Girl spent yesterday in underwear (she refused a diaper) with us running into the bathroom periodically. With wet underwear and only one poop falling in the hallway. But I got to thinking how much more convenient it would be to not have a gate. And, more importantly, it occured to me how I could babyproof & still have access to the stuff I need. So, viola! We may try to keep the toilet lid down, or keep the baby seat in it. I'll also make sure the 5yo doesn't leave water in the tub. But other than that, I feel pretty comfortable with it.
Thanks again for all of your insight, Mamas!!
PS. justKate -- we love Austin! Well, the hanging out part, not the driving through part. :)
