Definitely get her checked out at the drs to rule out any health problems. Then if it continues, you can get a referral to see a continence nurse who are trained to help people of all ages with their bladder issues. There may even be one near you who specialises in working with children. I took my DD to one of these and they taught her some simple awareness and relaxation tricks and the problem she was having got better. But first you need to get her checked out to rule out infections, kidney problems, diabetes etc.
