DDAVP, Desmopressin, can it delay natural dry nights?

My daughter is 7 and has been on Desmopressin for almost a year now.
She has been fine thru the day for years, but night time is a
different story. Desmopressin does seem to help, but not 100%. We do
try and limit liquids, no caffine, etc., take her to the bathroom when
we go to bed, but she still has 'accidents' at least once a week. We
don't use pullups, just a pad on her sheets to keep the mattress dry.
I know that Desmopressin is not habit forming, but could using it
delay drug free dry nights? Let's say that after a year of treatment,
she develops a stronger bladder to keep her dry. But if by letting
things run their course, if she develops the ability naturally after 2
months of toughing out the situation, I would prefer that.
She has no shame of the situation, we don't punish a wet night, we
praise dry nights. So I wonder if we should save the Desmopressin for
sleep overs, etc, and allow nature to take it's course.

Thanks in advance..
