Yes, that could be acutely embarrassing for a son to have to care for his mother's needs
Interesting that we should feel that Jalima. And I would normally agree.
Over Boxing Day - 27th DD’s PILs stayed with us and her MIL needs full care including toiletting. I can honestly say my SIL is a saint as he saw to all his mum’s needs with no more reluctance than he might at helping their 2 year old to use the potty or loo. He will dress or undress her, take her to the loo, help her up to bed, help her with bathing, take her by the hand if she does not know where to go just like a parent would with a child, but in a totally natural unobtrusive way. DD is pretty damn good with her MIL too and I was full of admiration. FIL tries, but is acutely uncomfortable with the elements of personal care, including bathing and hair washing so they have a carer in a couple of times a week for that, but SIL also drives over one morning a week to get her up, washed and dressed.
It was an eye opener to me.
