We decided to move the Saturday brunch activity to Sunday so we could go exploring some new bio shops in Prenzlauerberg (which had a great apple cinnamon tea) and since Kai had such a good time at the kinder cafe the week before it was an easy decision to visit again since it was on the way home.  Kai was having so much fun he stayed up way past his normal nap time, just like his parents (at least the way we used to be).
