I could not imagine having to wear diapers all the time as an adult.
I hope I never become incontinent and have to wear adult diapers because that has got to be a bad thing and it's likely very uncomfortable to have that wet diaper hanging off your hips and wrapped around your butt.
My son when he was 3 would go grab a diaper when he was wet enough or pooped and would bring me the diaper and tell me he wanted changed.
So he was uncomfortable wearing his wet or poop diapers and I would be too.
I can understand why he wanted me to change him when he was wet or poopy as that has got to be a bad feeling.
However I could probably eventually cope with having to wear adult diapers.
But I would say the cons are the diapers are uncomfortable, you have to bring extra diapers to change, the cost etc.
I was spending around $80.00 per month on my sons diapers until he potty trained and he went through around 5 to 8 diapers per day.
He was a very heavy wetter so he needed a diaper change more often.
It would be hard to walk in diapers, run in diapers, hike in diapers, ride a bicycle in diapers etc.
Then you have to worry about the diaper leaking.
I can't find any pros to wearing adult diapers all the time but the cons are easy to think about.
