My daughter is almost 5 years old. For the last 2 days, she has wet her pants once and almost wet her pants several other times. She sits still saying "I need to potty!" but says if she gets up to go to the bathroom the tinkle will come out. She has been potty trained during the day and night for over a year now. I have checked the symptoms of a UTI, and she doesn't have them...no fever, pain, etc. Could it still be at UTI, or some other problem?
