Some parents do put their older kids in diapers for long road trips.
I'm 10 years old and a boy and my mom puts me in Luvs size 8 diapers for road trips and I love wearing diapers.
I wear diapers all the time and so does my 6 year old brother.
My 6 year old brother wears Luvs size 6 diapers and I wear Luvs size 8 diapers.
Me and my brother both love wearing diapers and we both wet the bed and wear Luvs diapers for bed wetting as well.
So we asked our parents if we could stay in diapers all the time and they agreed and so now we are in diapers full time again.
We're going on a 500 mile road trip this summer and me and my brother will both be wearing our Luvs diapers and getting them changed on the road trip in our Van.
We also live in a rural area and me and my 6 year old brother also go outside and play on the swings and play in the yard wearing just our Luvs diapers and sometimes a diaper, shirt and shoes.
Running through the sprinkler in just our diapers also is a fun time.
