Mine would help me put the TENs machine pads on my back (I have endometriosis) get me a snickers bar from the stash, bring me a cup of tea and any pain meds.
My sons are 16 and 13 and if Dh isn't here they do the same. They understand it is painful, they have even run me a bath before.
We all look after each other. Caring for someone shows how much they mean to you.
I have been married 20 years. My MIL was an amazing woman and raised her son to be kind and considerate.
