Missy, it might be worth having a chat to your GP, as there are specially trained nurses called incontinence nurses, who help children who are having wetting issues. My DD went to see one when she was about 7 or 8, because she kept having tiny little oopsies. Helped enormously. There may be a number of reasons why your son's bladder is not behaving itself and it may have nothing to do with willful behaviour or laziness. Getting some help before he starts school could save an awful lot of shame and difficulty later on.
