my son 2 years and 9 montths. he was potty trained around 2 years old. after few months he got constipation and he refused to sit on potty because of the pain. we let him to do potty in diapers. we treated constipation. now he is out of constipation since 3 months. still he brings me a diaper when he wants to do poop. he use washroom when he wants to pee. but he doesn't sit on potty when he wants to poop. he cry if i make him sit. just after i make him sit and put him a diaper within 2 seconds he poop. i tried everything which i can make him sit to poop like distracting, making fun, reading, singing, rewarding, but nothing work. he scared to sit n poop. he even refuse to sit with diaper on. i hope to get any solution from a doctor or parents who went through same situation. thank you
