there may be no problem at all. many children do not achieve full nighttime dryness until age eight. assuming she does not have any underlying medical problems that are contributing to this you can just wait it out a bit longer. trying not to make her feel that she is responsible. talk to her pediatrician but most conservative clinicians may just recommend watchful-waiting at this time.
my 5 yr old daughter pees out of her pull-up every night. no drinks last 6pm bedtime at 9. what is the problem?
