It was planned like a military operation, and TBH I’ve never dreaded anything so much in my life! For some time my poor DM had been very reluctant to leave the house at all, so we had help from the GP, who prescribed a mild sedative, IIRC Valium. Elder sister (who lives a 5 hour drive away) stayed the night before, and surreptitiously packed a bag for her.
BiL was already there, Dbro arrived on the day - we told her we were all going out for lunch. The care home (a 60 mile drive away, very close to where I live) had said that arriving for lunchtime would be best.
Sister and I drove her, Dbro and BiL were following later, with some smaller items of furniture for her room.
All the way there I was freaking out in case she twigged, and demanded to go home! But thank goodness, no such thing happened.
I really thought she’d twig once we arrived at the CH - you’d think it’d be obvious! - but I dare say it was a measure of her dementia by then that she didn’t. We were all shown to the dining room, and given a very nice lunch - again, I really thought she’d twig, but evidently thought it was a restaurant and wanted to pay!! You can imagine how we felt! (Her ccs were no longer valid anyway, Dbro and Dsis had taken over PofA for finances well before.)
After lunch, and a little walk in the garden, DSis was brave enough to tell her she was staying, I don’t think I could have done it! BiL and Dbro had meanwhile put the familiar items in her room. She wasn’t happy, but didn’t actually kick off.
TBH it went better than we’d dared to hope.
I wish I could say she settled happily and quickly, but she didn’t - for ages (almost until she’d stopped recognising me) the first thing she’d say was, ‘Have you come to take me home?’ - home was of course sold to help fund the fees. And TBh she forgot that anyway - the home she often spoke of later was the one she hadn’t lived in since before WW2.
But it was an excellent care home (an Abbeyfield specialist for dementia) with lovely staff, and we were very happy with it. She was almost 89 before she moved there, and went on for another 8 years. Which to me - although she did have the general constitution of a rhinoceros - is a good indication of the care she received. TBH I often wished she could have quietly died in her sleep before we had to put her through all this, but by then there was simply no alternative and because it was such a momentous decision, we’d left it rather late anyway.
I wish you all the very best with your own parent! I know all too well how hard it is.
