Some 12 year old boys wear diapers.
12 year old boys wear diapers either for need, for incontinence, bed wetting or even just for fun.
Although the majority of 12 year old boys are potty trained and out of diapers some 12 year olds do wear diapers.
A lot of 12 year old boys love to wear diapers and a lot of 12 year old boys wet the bed as well.
A diaper is also a good idea for a 12 year old or younger or older kid to wear on long road trips as well.
Diapers are very comfortable and are great to wear and it's better than holding in the pee or poop.
