A friend of mine was told by their local GP that her son was too busy playing or otherwise occupied that they “hung on” and didn’t go to the toilet when he should. When that happens the moisture gradually leeches out of stools and they become hard to pass. At that point is painful and a child will not persist. My friend used a reward system to encourage him to go instead of hanging on. When he got into a regualr routine of going when he needed to the constipation problem ceased. He was already getting plenty of fibre and drinking plenty of water.
