Wendy called again tonight, dad is doing worse. His blood sugars fluctuated today between 22 which is very high and then right down to 3 which is horribly low. I think 5.5 to 7.8 is normal. They've moved him into a different ward. They don't seem to be able to keep his blood sugar levels under control, even under constant supervision in hospital, so how could he possibly go home. No chance of that happening any time soon. Very worrying.
