12 year old dd who is autistic keeps saying she can't wee on the toilet and is wetting the bed as she's saying that's the only place it comes out! I'm scared she has a uti but she says she's not in any pain. I know if I call the doctor they will ask for a urine sample which will be impossible. She also hates the doctors with a passion so trying to get her there will also be impossible. Has anyone else had this ?
