I have been using Persona for a while now and don't hesiate to perform my pissy tests in front of my 3 year old DD. I went for some swabs with the nurse and took her with me, she watched avidly. The next day I caught her with my pissy persona stick trying to 'test' herself lying on the bed with her legs wide open!! She said 'just like the nurse does'!!!!!!!!!!!!!!!!!!!!! God, I thought she was innocent!!!
