Thank you for your query.
I hope she was not on diapers after the age of one.
This is a common cause of concern in babies on diapers.
They are unable to express themselves because they were comfortable in wetting themselves in diapers.
If that is not the case this is a case of pervasive disorder....consult a psychologist
Consult your doctor if the problem persists.
If you have any further queries you are free to consult me.
Hope this answers your query.
Wishing a speedy recovery.
Have a nice day.
