Hi !My son is 3 year 6 month old .He never tells when he poop .He used to hide from us and then poop in standing position in the shorts itself .Due to which he used to poop 4-5 times a day but doesn’t tell even after that too .Every time we have to check and if we somehow manage to make him sit on potty seat he doesn’t poop there properly .We had tried every way to potty train him .But all in vain .pls suggest
