I have talked about toileting on this site a couple of times. My Son who’s nearly six is being toilet trained, which is a very long process. There are times when he needs to urinate or open his bowels but he runs away from us and hides rather than sit on the toilet, he will giggle to. Could this be because he likes the feel of wetting or soiling himself? he wants a reaction? or he is anxious about using the toilet?
