My 82 year old mother has cognitive impairment due to ruptured brain aneurysm 25 years ago. She currently resides in a nursing home. She is in poor health, unable to walk, and needs two people to care for her personal needs. I am her POA and visit her regularly. I have two sons getting married this year. One son sent her a Save the Date card and invitation as a gesture of love, knowing that she will be unable to attend. The other son did not. This son sends my mother an annual Christmas card with photos of him and his fiance, but he does not visit and did not send her a Save the Date card. I am disappointed in my son for not considering his grandmother. The relationship with my mother and stepfather and this side of the family has been difficult over the years, and my sons do not have a strong attachment to my side of the family. However, out of respect for my mother (and for me), I think my son should be more caring. Any thoughts?
