I wore diapers or cloth training pants with plastic panties to bed until I was past my 11th birthday. I outgrew the diapers around 10, so after that it was the trainers only.
These were a night time thing only, but there was one exception I can remember. I think I was around 7, and we were going to my grandparents farm which was about a 4 hour drive away. I can't remember exactly why, but we had to get there early as my dad was going to a funeral or something that was a couple of hours drive further on from there. He was taking us to the farm first, then leaving with my grandfather from there. He wanted to get to the farm by 7am, so we had to leave by 3.
We packed the car the night before, and I went to bed early, wearing a disposable nappy. I was woken up at about 2:30 by my mother, who had made me some breakfast to eat before we left. I hadn't wet during my sleep, so mum took my dry nappy off and took me to the toilet first. I ate some toast, and we prepared to leave. Mum called me back to the bedroom to get dressed, and she had my clothes laid out. I was to wear red sweat pants with a t shirt and a jumper, socks but no shoes. I'd take my sandals to slip into if I had to get out.
She also had my still dry nappy that I had wore to bed the night before.
I was very tired and groggy, and didn't quite understand why my nappy was set out. Mum told me I would be wearing the diaper in case I fell asleep and had an accident in the car. I didn't want to, and I remember carrying on a bit about it. That soon stopped after dad came in and told me to shut up and do as I was told.
So I lay down, probably crying a bit, and mum put my nappy back on and helped me dress, and we left soon after. I must've fallen asleep for a while, but I do remember waking up and the sun was shining. I needed to pee, but hadn't wet myself as I slept, so that was a bonus. We were only about an hour from the farm, and I told my folks I needed to do a wee. Mum asked me if I was already wet, and when I said no, she said we would stop at the next rest area.
I vividly recall asking her if I should just use my nappy instead, and dad getting cross with the idea, and telling me my nappy was only in case of an accident, and not to use for laziness, then mum telling him not to get mad with me as I hadn't been lazy, and in fact had managed to stay dry.
We soon pulled over in a look out type area with no toilet facilities. Mum came around to the back seat where she pulled down my pants and removed my diaper, then took me off to the bushes so I could pee behind a tree. She threw the diaper in a bin there.
The other clear memory I have is returning to the car, and realising that I didn't have underpants on now, and asking to put a pair on. Dad said no, as all the clothes were packed in the boot of the car. That was the first time I really remember "going commando" and it was something that really stuck with me.
But that was one of the few times I remember wearing a diaper whilst not just in bed at home.
