Colin Cliffe writes from Houston, Texas, with the latest news of Berni's treatment: "It's very good to know of all the support back at home. This has been without doubt the most difficult five weeks of our lives but as I keep telling Berni, all this pain must give us some gain.
"I think we are turning the corner now as Berni is walking more and more. The only major hurdle now is the eating. She struggles to eat anything substantial and even then to keep it down.
"They are giving her even more meds for it and hopefully it will be better after the weekend. We will have to stay at least one additional week if not more.
"Will keep you informed."
