@ApplesAndPearsStairs from my perspective we were told in the November/December my mum would need a transplant.
We had to go to a meeting with the hospital where you watch a presentation to explain which I think was in the January. Then the work up process was a few appointments of various bits - blood tests, made radioactive (only for a while lol) I got the match/ok to go ahead in June, and we were scheduled for September. We then had meetings the week before with the Human Tissue Authority etc to make sure not being coerced.
Whether this process would vary for altruistic donation I'm not sure,
Recovery - has the op 22nd September - started a new job 24th October (although I had to see occ health to get Ok) but as first 4 weeks were classroom based training it was fine, a bit tender but could move/walk.
Post op, we had it Thursday, was up/walking Friday and released Sunday.
I didn't have children at the time - I do now. I went to live with my sister for 2 weeks until I could drive and Tbf I did feel like I'd been hit by a bus during that time. Slept a lot, wee'd a lot, you definitely need support
