I am trying to do potty training for my son, he doesnt sit on toilet seat, or small potty seat , when he urges to pass motion. This causes stool hardening. He has a habit of doing by standing and only in diaper. So i am trying really hard, not forcing him . but still, the moment i try to make him sit , he resists , stiffens his leg , doesn't sit at all. Also, feeding him, is not very easy, he resist to eat most of the time, even in all other days. no matter how much i try to make him eat or drink, as of now he will not co-operate much . how to make a child sit ? is there any laxative i can try to help him to pass motion, and avoid stool getting hard more.
