DS will be two and a half at the end of the month. He's shown no inclination to be potty trained. Nursery suggested trying him with trainer pants acouple of weeks ago, he screamed the place done and refused to have them on. The next day the managed to get them on (bribery with stickers), but he just carried on as before and wee'd in them. He'll sit on the potty, but won't do anything in it, then get up and wee straight away. Is this normal? any suggestions?
