Age two to seven and years long gaps until I was 18, I wore here & there once a month or so in to my mid fortys. I am 57 now and have at least slept diapered 98 out of 100 nights for over the last 13 years.
I was in nappies day and night until I was about 5 and still at night until I was 8 or 9. I went back to nappies at night at about 15 because I still regularly wet the bed. I wore nappies at night until I was in my early 20's when I finally became reliably dry at night. I went back to nappies at night in my late 40s when I started wetting the bed again and now wear them 24/7 as I have very little bladder control due to my diabetes
