diaperer

noun

1. (agent, form-of, uncommon)Agent noun of diaper; one who diapers.

   “It is pretty hard to make a mistake when diapering a baby. About the only way a person can go wrong is to put the diaper on backward, a condition that neither the diaperer nor the diaperee is likely to notice.”

   “Early on in the lives of the rising generation family members, the kids are the diaperees, and their parents are the diaperers. At the other end of the escalator, a role reversal naturally occurs. Hopefully, the former diaperees will be able to pay someone else to become their parents' diaperers, but I think you get my drift.”
