Don, smacking a child for wetting himself serves No purpose you are only making that child feel more insecure more unloved !and in later years may resent you for doing it ! have you asked him why he does it?it could be lazyness but I doubt it unless he is doing it for attention ! but yet again i doubt it if a child was dry and wets itself during the day again having accidents then there is a reason could be bullying an infection in the urinary tract could be that he is a nervous child ! it can be any number of reasons try and get the one who is most closest to him usually Mum to ask himwith love and effection.
