Am so happy for you, AngeMorange, and for your Mum! Sounds like she settled in quite well and is in the perfect place.
Short visits with my husband are best, too. An hour or two at most. He can only stay awake for so long before his eyes close and he's napping again. I have been going twice a day (only 20 minutes away) but am thinking of cutting it to once a day twice a week and twice a day the other five. After I see how that goes I'll go once a day more often. Then, at some point, I would like to go on holiday to visit my son and his family for a few days. Will arrange for Bob's brother and best friend to visit regularly while I am away. He does not remember my visits but is always glad to see me. I think I will feel guilty not visiting twice daily. Guess I'll find out.
Glad that things are working out for you Barb. But visiting, like everything else, is not a "one size fits all" affair. As we'd been airbrushed out of a lot of our friends lives when AD took over, there were only a couple of people who visited him, other than me. I went most days, but if someone else was going, I didn't, and the length of my visits depended on him.
I once sat for an hour, whilst he was asleep, because I felt I should. But then I realised it wasn't helping either of us. So, if he was awake, I stayed longer, but if he was asleep, I'd stay 5 minutes (the Home was very near to me), and return later in the day. And then usually for less than an hour.
For the first few months he was talking, though it was a load of nonsense, but after 3 UTIs he went downhill, and didn't talk, know who I was, and would stare over my shoulder whilst I tried to make conversation. When he stopped eating, and his food was pureed, I would visit at lunch time and tea time and try to feed him, but after a couple of weeks, it was felt it best for him to stay in bed, and he died soon after.
If you feel it's good to have long visits, that's fine. If short visits are more suitable, that's fine too. Everyone finds their own level, depending on their situation.
