I’m not posting for advice, I just need to get this off my chest.
My MIL has no idea that her son is her son. We went out with them today, bought her a card for her Birthday. Addressed to “Mum” she stared at it and said “Mum, who’s Mum?” We gently explained she was DH’s mum but she looked so blank and confused, as though we were having her on. I looked over a little later and she had tears in her eyes. She’d made comments about being called Nanny by DD but we though perhaps there was another name she wanted to be called.
When we collected her and FIL today she’d been looking for a photo of “a little boy on a bike, it looked just like (our daughter)” the boy on the bike is my DH of course.
A few years ago she stopped being able to remember his birthday.
Then last year at Christmas their card was signed off with their names, not mum and dad.
Then at birthdays she’s addressed the cards with her name at the top rather than at the bottom.
When DH called to say we’d had the baby he said she sounded vacant and non plussed.
We gave them dd’s birth announcement card and she asked why the baby had our surname - she couldn’t remember her previous marriage.... and it would seem having a baby boy in that previous marriage that she absolutely doted on and loved with all her heart.
I feel desperately sad for DH. I wish there was more I could do. It’s so sad to think we have to watch her deteriorate now... she was always so lovely and sharp as a tack, I feel absolutely saddened to the core.
