The key to bladder training is to *not* give into the urge to pee right away so you can gradually make it hours between bathroom pit stops.
I spent long days and long hours trying to find the perfect pee funnel. I even keep her nearby if I have to pull the van over for a quick pit stop.
Admit it, you've peed in a bottle or at least thought about it on a road trip. It's only inevitable to want to relieve yourself in the car to avoid losing.
So last year, the city tried a new tactic: walls that pee back. As part of a new initiative called Pit Stop, they've started installing toilets across.
