Hi so could someone please help me. My son started school last week hes been doing great. Apart from one problem, he gets very upset as he said people walk in on him using the toilet. I undressed they can't use locks due to the children locking them self in. But does it sound right that people can just walk in on them ? Has this been a issue for anyone else ? If not how do they do it so I can suggest they change things. Any help please ?
