If you look at cute diaper art you'll see that the diapers are at least 6" thick and would probably hold more pee than you could pass in 12 hours. I'm not talking about that kind of thing where the diaper is basically a huge bean bag thing, but more like... Just a really, really thick diaper. Why aren't these a thing? They would make an awesome 'special occasion' diaper. Even if they were $10 a diaper, I would still buy a pack of 10.
If a company tried to make these, I dunno, 'super-diapers', do you think they would succeed? If not, why? Production costs, lack of demand?
