Don't you want to see her, at least one last time, before she passes away???
She already has Dementia etc.
It will get progressively worse.
She is not mobile, and cannot travel across the country herself.
She needs, care taking for her health issues.
It is a matter of conscience.
You bite the bullet and you all go see her, even if she may not be totally 100% cognizant of your baby or you or your Husband.
Or, you send your Husband only.
And you decide what to do, knowing that, one day she will not even be here in this world.
My late Dad, was very ill before he died. We ALL did constant care taking for him. It was arduous. EVERYDAY. And you know, some of his immediate relatives, could not even MAKE the time, to come visit him. At all. They said they were busy, lacked the budget etc. And barely even called him. He was very, sad about that. I saw him.... being sad. It was heartbreaking. Very heartbreaking for him. He did a TON for his relatives while he was able bodied. And then, when he was sick and ill and going downhill in health, they could not even make the time or the trip, to come see him. And he would ASK them to come see him. They gave all kinds of excuses. And MEANWHILE, these same family/relatives... were taking trips and going on vacations all over the place. But could not even make time, to see or visit my Dad.
When a person is ill and dying... that is when you see a person's real level of caring or not... and their sense of graciousness or not.
And because of the way my relatives acted... while my Dad was ill and dying and still not visiting him... I DO NOT HAVE warm feelings about them. Anymore. Then they finally showed up... but at my Dad's funeral. that still didn't mean much. Because while he was sick and ill and dying... they made NO time, for him. Not even phone calls.
Think about it.
Your Husband's Grandmother, is on a downhill spiral per her health and cognition. It is either an inconvenience matter or a matter of conscience.
Being old, ill and lonely... is a VERY HARD THING TO BE. I saw my late Dad... going through that, because of his cold relatives. His friends were nicer to him, while he was ill.
When a person is in that state of health... and diminishing mental capacity... per my Dad... YES it entails just SITTING with them for company and companionship. THAT Is what you do. FOR them.
It is, called "compassion." For the ill and dying. And love, for them. And showing it. While they are still, alive.
I'm sorry this is hard for you.... but my heart breaks, for your Husband's Grandmother. It makes me remember... my late Dad's.... heartbreaks too, before he died. And his family not even giving him the time of day.
I would often, just sit with my Dad.... just sitting there WITH him, for companionship... so he would not be lonely. And just showing him, that he is not just an inconvenience. That he is still loved. Even my Husband.... did these things for my Dad. And even would drive him around, just so he could get outside. My Husband... would stay up late at night... just sitting with my Dad too. Just for company and making whatever conversation he could, with my Dad. My Dad had had a stroke too... so he could not talk, fully. But he still could say some things. He was a human... and we loved him.
My kids.... talk about my late Dad often. They love him. They did not know him. But they remember him, because he is still a part of their lives. And they love, going to the cemetery, to bring flowers for him. Now.
How does your Husband, feel about this?
Traveling with kids is never easy.
But your Husband's Grandmother, is 90... years old.
Just how much time, has she got?
