#PottyProblems.....

My son is 3 1/2 years old (we have been on this journey for a while not sure if it is something I am doing wrong or what) and still does not want to go potty all day long (please tell me I am not the only one out here) he will do it for a while but then he decides enough is enough.. He is very smart I KNOW he can do it and KNOWS how to do it, he is just stubborn.. I have tried many things like if you go you can have a cookie (he goes just to get a cookie then never goes the rest of the day), then I tried telling him if he goes all day to the potty he can have 2 cookies after dinner (2 cookies must not be worth going all day cause he never does), also told him he could go to school if he goes all day (he says he really wants to go to school but he does not potty all day) and even tried telling him he would get a toy (he must have enough of those too).. I have even put him in his underwear all day so he will get the feeling and by the end of the day he has gone through EVERY pair of underwear he owns!! We have tried the big potty with a seat the little potty that talks, dvd's, books what else is out there? Only thing he has not done is go outside like our dog which may be an idea because today he told me "momma if I a dog I go outside to pee" hmmm may have to try that when the weather gets nicer here.. Of course every one tells me not to worry about it (not sure if they are just being nice or if they mean it) that every kid goes when they are ready my dad actually told me "don't keep worrying about it I don't know of any kids that have went to school in diapers" (well his grandson may be the first).. Not sure what else to do about our situation guess I am going to be the only mother of an 18 year old that has to wear diapers..
