First thank you all so much for your kind wishes. It really helped to know there are people who care.
We are back at home again and it seems that the worst is over. Monday we were at the hospital again for a final test and the results were fine. The little one is now much lighter and can enjoy breast milk again. Fortunately we were at the hospital only for two days. Otherwise I would have gone crazy.
Now I only hope the little one will have let me some time to update the blog more often. He is two months old already. The time really runs. Hope you have a nice day!
