I had some occasions where yes, I got a choice on whether I wore nappies. I wore nappies in the day until I was 5, then for bed until my early teens. After I was potty trained in the day, there were times that I’d still wear a nappy for safety or convenience such as when travelling or when i was unwell.
One time on vacation, i think i would have been 8 or 9, my mum was changing me out of my night nappy in the morning and getting me cleaned up for the day. We’d just arrived so we’re going out to explore for the day, so lots of walking and never quite being sure where the next bathroom will be. As she was cleaning me up, she stopped for a second and then said (paraphrasing words slightly) ‘we’re going to be out and about a lot over the next few weeks and I don’t know where we’ll be able to stop for the bathroom. I want to give you a choice, but it is a choice and I don’t mind which you go for, it’s totally up to you, but whatever you choose will be for the whole holiday, so we’ll choose now and then stick with it. We can either go with your big boy pants pants (holding up) and hope that there’s bathrooms where we need them and you can hold it ok, or… (swaps the undies in her hand and holds up a fresh nappy), we go with daytime nappies, just for holiday, and then wherever we go you‘re totally safe, but of course you’ll be in nappies and all that comes with that, which you know. It’s your choice and what you choose will be for the whole holiday - it’s up to you.
I lay there for a second and ummed and ahhed over it, we chatted it through a little, I liked pants as they gave me more freedom, but nappies were safe and they meant no accidents. Mum pushed me for an answer as we needed to get going for the day, holding up a nappy in one hand and a pair of pants in the other. I thought for a second and then (primary thing being the less chance of accidents as I knew we’d be out and about a lot), I pointed to the nappy. Mum checked with me ‘so you‘d like to wear nappies for the holiday, i the day as well as at night, that ok? You‘ll be in them all the time’ - I replied with yes, she then said ‘well either way would have been fine with me, but I think you made the right choice, this way yes you’ve got nappies which i know can be tricky, but no accidents and that’s so much better’ - she then changed me in to the fresh nappy, put all the underwear away in a suitcase as I wouldn’t need it, got me dressed and off we went. First stop that day was a store as we only had enough nappies for nights, so went to find some more and then I spent the whole vacation in nappies!
