where to go next....our son is three and we have been trying to potty train him for a week now but with no success. In a typical day we are getting through 12 changes of clothes ! He has now started to say sometimes he needs a wee but instantly wees in his pants...we are having no success on the potty. He wont tell us when he is pooing and still goes to hide instead and does that in his pants. I cant see us ever leaving the house again!! any advise.
