I have been on about this before and am hoping I can once again pick some brains. My 3 year old ds refuses to sit on the potty or toilet for a poo I havr brought various different types of pottys and seats, tried rewards, star charts everything! He knows he needs a poo just insists its ok to do it in his pants has been dry day and night for a year. He starts state nursery in September and I am really anxious to sort this out before then. HELP.
