I have a range of ages, depending on the mood I'm in.
I'm not at all into being really young. The bottles, pacis, plushies, and sippy cup ideas don't really interest me. I'm definitely more of a big kid! I think for the vast majority of my little time, I am between 9-12. But sometimes accidents happen, and to my "horror", I may wet my pants.
If it's diaper time I'm looking for, I'm still older than the normal suspects. I'm around 6-9 and wearing a nappy for bed wetting issues. It will probably involve me putting one on before my bedtime, but staying up a bit late and using it, or waking up first thing in the morning with a wet diaper on, but leaving it on and using it again while I watch cartoons or eat breakfast or something.
Sometimes I might "crossover" with my ages, and be an older child of 10-13 who wets at night, and has to wear a diaper for a long drive or flight for example, in case I fall asleep during the trip. My older little in this bracket has also been sent home from school for wetting his pants before, and has been diapered at home for punishment!
So it varies a lot depending on my mood. But usually I'm an accident prone bigger kid.
