My daughter is 3 years old. She recongnizes whenever she needs to pee and also when to pass motion. She tell us to take her to toilet for pee. But whenever she wants to pass her motion, she stands in a place and want her underwear on while she passes the motion. If i take her to toilet or remove her underwear or make her sit for motions. She starts crying a lot and stops the passage of motion. I tried making her understand by all the means but she is not buying anything on this. i am unable to understand that what problem she is facing to pass a motion in toilet by sitting when she is ok in peeing by sitting in toilet. please help on how to make her pass the motions in toilet.
