I think the English word is "pom pom" - but "Puschel" is how we call it - and which is at the moment the most cherished word of the triplets.
Never in my life I had dreamed that I would wear a cap with a pom pom. (You can remove it by a big snap fastener).
When I went to Berlin for Christmas I promised to send photos to the Little Ones - so you see the Pink Puschel standing in front of the Literatur Café, in front of the Charlottenburger Schloss, the manor house in Britz - and so on. They loved it.
