I used to use my daughters pull-ups when things were really bad- I'd
open one up & line my underwear with it. It worked well enough! I'm the sort who generally pulls over to the side of the orad & goes just about
anywhere I can, when I feel the urge. So far no one's busted me! Nowadays, I use extra long heavy panty liners, just in case. I haven't had to wear the actual diapers in a long time, but they do give you great peace of mind. And I always have a car kit with me- ziplock bag with extra underwear, extra pads, baby wipes, & empty ziplock baggies- just in case! Oh yeah, & a pair of yoga pants that can be worn just about
anywhere, if I ever need them!
