I Just use baby diapers to use them. I of course don't fit them or put them on, I just open them up and go into them. For various reasons its much more convenient than going to the only bathroom here. Cups and stuff doesn't work. I can't always be able to wear my Little Paws diapers from ABU. I usually go for huggies overnights. I may also from time to time try other brands or product lines. I also used to fit into goodnights very well, not anymore. They have shrunk them. Now I just use them in emergency, like if I have to also BM I will put them on and stand there and fill them then take them off. They work great for that, though I try to use a baby diaper beforehand by just holding it back there.
