I enjoy changing my own kids diapers as well as my 8 year old autistic nephews diapers.
Sometimes when I am at my nephews house or when he's over here I've changed his diapers.
My 8 year old nephew is not potty trained as he's more severely autistic and wears Pampers Baby Dry size 6 diapers.
I change his diapers and enjoy doing so.
My 8 year old son also wears Pampers Baby Dry size 6 diapers for bed wetting and I change him into his Pampers Baby dry size 6 diapers at night before bed.
I enjoy changing his diapers as well.
