I guess you husband is doing this because , you , that pious lady or any other lady are not willing to help him out. But again he is not the only man on the face of earth that is why he has to do it. He can look for some social worker, or hire a lady nurse for giving bath to grandma. How difficult it is for him to find a woman to help him out with this chore ?
i am willing to help my husband but first of all his grandma wont listen to me and she would just swear at me and we did hire some private social care takers and she would come like 10 am and when she would take her to bathroom my husband grandma wont listen and they would have just left without doing anything she only listen to m y husband and my MIL but my MIL is not ready to give her own mom a bath when she can
