We have started potty training our 22-month-old son using the Naked and $75 method. So far, we have only had accidents. And no use of the potty. He doesn't seem to care if he wets himself (wearing thin underwear or naked). He doesn't say "uh oh", like he hardly even recognizes an accident. We have all been very calm but stating poop and pee go I the potty after each accident. What should we do?
