My four year old son has been wetting and soiling himself.

My four year old son has been wetting and soiling himself. He stays dry at school but when he gets home he doesnt use the toilet. I need advice please, I feel loke he is doing this out of laziness. He picks and chooses when to use the bathroom.

You four year old son is still young to be 100% toilet trained. I suggest you try to work with him and see if anything is triggering his incontinence. It may be diet. Also prompt him to use the toilet and when he does reward him as this is the behavior you want to see.
