I wore diapers on road trips when I was a baby and toddler.
But now as an adult I no longer wear diapers at all so no I don't wear diapers on road trips.
My kids when they were in diapers wore diapers on road trips until they were potty trained around 3 years old.
So yes I've changed my 3 year old kids diapers on the road trips but I did so in the privacy of our mini van or in the trunk of the car.
I never changed my child's diapers in view of the public because they deserve privacy as well but yes they did go without pants and wear just diapers on road trips as well when it was hot.
I loved watching my toddlers and 3 year old kids run around at parks and rest areas wearing just a diaper, shirt and shoes.
It was so cute and I have pictures of it and video of it as well.
My kids are now out of diapers so they no longer wear diapers at all so they don't wear diaper anymore on road trips.
