I'm so worried that my dd won't be able to go to preschool in September because she isn't toilet trained. She has just turned 3 but completely refuses to sit on the potty or toilet. She is showing some signs being ready but the few times I have tried to potty train her she hasn't managed to even sit on the potty for longer than 5 seconds. I now feel under a lot of pressure to get her trained before September. Has anyone else had this problem? Thanks
