Help! I just got a kit in the mail for a 24 urine sample for my 18 month old daughter who is not yet potty trained. I called my ped endo's office and the nurse was unavailable to answer my question so I am asking you guys. Has anyone had to collect urine from a child who wasn't potty trained? If so, how did you do it? I know when she was in the hospital for vomiting they collected a urine sample by taping a "baggie" to her and that seemed to work fine. They didn't send any baggies with the kit. Is there somewhere I could get these baggies or is there something eles that works? Thanks for your input. I will let you know what the nurse says when she calls back. Laurel
