I have just spotted this post I am sorry you didnt get any response earlier, If your Mom has visited you by now I hope it was successful, I liked the idea of getting her to help you with small tasks, makes her feel useful,walking with her is a good thing enjoying the outside and natural enviroment helps, nature is a wonderful soother.Comfort and just being there for her is the best thing,I wasnt able to do that for my mom as she was in England and I was in the US I have always regretted that ..it haunts me to this day.. It would be great if you were able to visit her more you will one day be very glad you did so, today is hard for me.
