My mom made me wear just in case diapers once when I was 10. I had wet the bed up until I was 7 or 8 and didn't think anything about it when I had to get a diaper on before going to bed. When I stopped wetting, I stopped being diapered at night. One day when I was 10, we were going to be going on a long trip on a plane. Mom did not know if we would be able to use the restroom during the trip On our last trip we could not because of turbulence most of the way. I ended up almost wetting myself on that trip, so Mom thought that it would be better for me to wear diapers.
I was not too happy about it, but I had no choice. At the airport about 1/2 hour before we boarded, she took me into the family toilet and made me take off my panties after I used the facilities. She then put me in the diaper (it was a youth sized attends). I felt self concious about it, but it was on and there was nothing I could do about it.
Even though I was able to stay dry on the way out, Mom made me wear one on the trip back. A couple of years later I was back in diapers at night again and now I am in them 24/7, but back then I was not too happy about it.
