My 5yr old just started kindergarten and refuses to use the bathroom. There is one right off her classroom, but she won’t use it. Now, this is a child that has never had any issues using public restrooms. Ever! So, when I pick her up, she’s about to burst. I told her that it’s not healthy for her body to hold it all day. Should I ignore the topic? Or tell her the doctor said she has to use it.
