#AskTheExpert My baby boy is 3yrs 1 month old. he is used to doing potty in diapers. He doesn't use diaper for peeing or while sleeping as well. all day no diapers, he speaks and informs us for pee and other things, and even for potty he says give me my diaper, but when we ask him to poop sitting on seat, he doesn't do! Holds his poop until diaper is put. If we don't put diaper, he holds it more! how can I get him do potty on seat?
