My little boy is 2 years and 5 months I have tried to start potty training and he does sit on it but he doesn't like his trousers off and he wets his trousers. Unsure what to do. I ask him every 20 min to go potty and he just says no and does a tiny wee but then wees in his trousers. I have been through six trousers so far this morning. I am also worried about taking him out.
