DFIL came out from hospital for his 70th birthday, planned as an afternoon visit. DSIL (married to the middle son, works in related profession but in the community) arranged for a hospital bed at home, "just in case", but things had moved fast and everyone else knew he wouldn't be coming home again by the time it was delivered - he was going to hospice as soon as abed was available.
But on the day of the party, bed had arrived and it was seen as useful to have in case a rest was needed. Which it turned out was a good call.
But then DSIL got DBIL all het up (middle son) about "dad is enjoying being home, he should just stay the night". No thought of the significant care needs for a large man who was no longer mobile, in pain, had significant meds needs, and who did not want any family doing personal care when he was still coming to terms with it having to be done for him. (We had gone from mowing the lawn to never coming home in about 4 days and this was less than 10 days later).
It caused huge upset in the family. Elder son (DH) and daughter could both see DFIL was deeply uncomfortable both with the thought and physically, but couldn't stand up to DDIL. DMIL was beside herself and had let herself get swept along with the hope he could stay but hadn't faced the realities of it, so got terribly upset about it all. The DGDCs were all terribly confused and upset (4, ranging 9 to 3). The 2 who started it all lived next door and bailed out when the going got tough every time and walked out again that time leaving chaos behind.
Instead of DFIL going back to hospital having had a nice day (which he'd had, and he was happy, or maybe resigned and accepting might be a better way to express it, to be going back to hospital - but not upset about it before it all kicked off ), he went back late, terribly upset about it all and about the chaos caused. And late for his meds and in more pain than he should have been.
It caused a lot of upset and certainly changed how DH saw his DB and DSIL.
I say this not to cause upset but to show that there are plans that can be put in place to go out, if physically practical and possible, for the unwell person to enjoy something suitable to their needs at the time but not putting too much pressure on them or the supports available.
So planning for afternoon tea somewhere, maybe even at DM's home, but with sufficient support to manage her needs while there, might be great. Or a car trip to see some places of local beauty she's always loved. But planning a 3 night stay could be way too
Much for her ans you all, especially without the trained support she'll need.
