In reference to getting a parent dressed or undressed and attending to personal needs what is the din for a son helping his ailing mother?
Answer:
This is also fine, where necessary.
Although we are of course generally careful not to see parents' private areas, it is permitted to do so where there is a need for taking care of them. Please see here for more details.
The issue of hirhurim will of course not, in general, apply to such circumstances.
Best wishes.
