My grandmother is 90 years old. My mother is a nurse & she is the one responsible for giving her a bath. The last time my grandmother had a bath was approx. 1-2 months ago because she hates getting a bath & puts up a fuss every time. My mother deals with it by letting her go & getting her own way, instead of putting her foot down & setting the standards whether she likes it or not, is this the right way of handling the situation? Also, is 1-2 months without a bath acceptable, when her hair is greasy & she looks dirty?
