Hello querrty
This must be so frightening for you (and dad), I do think that once transfusions are needed then you have turned a corner that isn't welcome. All you can do is love him, give him as many good days as he can cope with, give him hope and enjoy your time together. There is no time frame that comes with this but it is a marker for difficult times ahead I think. I know it's something that I dread, my hubby goes from 9.5 (in the old method) to 11.5 and is ok on that. I do dread the day it drops below and he needs a transfusion. On the plus side it can really boost the person and give them more quality of life. I'm sorry if I come across too gloomy, I'm a realist and I think it's important to know what you are facing, you can then decide whether to face it or not.
Hugs from our forum brethren, maybe it's time you had the comfort blanket for a while. In case you don't know, this is a virtual blanket that we share around the forum between those who need comfort. It's full of all the love and hope and comfort people here share and boy, does it give you comfort.
Love
