K.M.
Does she have allergies? I grew up having allergies and I also had to use the bathroom frequently- even sometimes having accidents at night up until 10 or 11 years of age. I think the doctor said something about the allergies making the lining of the bladder swell and making you feel as if you have to go more frequently- just something to think about- I still have to go more often than most folks, by the way, so I just try to limit liquids, especially when driving a long way! Good luck-
