I would rather servicing five babies than one adult. Adults are heavier. Also. babies are born sterile, whatever infection they can have on them comes from the adults. Finally, you watch a baby grow stronger, while I (we) deteriorate. (That affects the caregiver morale)
Yes in fact I was doing humour not real commentary. I never had a problem with changing diapers. I never hated it and I did it lovingly and willingly. Even as a kid with my (10 year younger) baby brother.
Adult diapers and/or even just the general process of dealing with parents in their physically declining phase is a whole other story. I also know all about this.
I changed a lot of diapers.
